OverviewThis study uses ANSYS Fluent software to simulate blood flow through an occluded artery via computational fluid dynamics (CFD) analysis.The model features a bifurcated blood vessel with stenosis (narrowing) at its center. Blood properties are defined with a density of 1060 kg/m³ and dynamic viscosity of 0.35 kg/m·s. The stenotic region is mathematically defined using a curved function.The primary objective is to analyze blood flow behavior through the narrowed section. Blood enters through two inlet branches at a combined mass flow rate of 0.002385 kg/s, while vessel walls are treated as rigid boundaries.The model geometry was created using ANSYS Design Modeler and discretized with ANSYS Meshing, employing a structured mesh containing 85,222 elements.MethodologyThe vessel stenosis geometry was generated using a parametric curve function defined by the equation: y = 0.0002475cos(πx/0.001), which describes the coordinate points forming the narrowed profile.As an illustration, a 30% stenosis indicates that the constricted diameter is 70% of the normal vessel diameter.To evaluate fluid behavior under varying conditions, the stenosis severity was systematically varied across seven cases: 30%, 40%, 50%, 60%, 70%, 80%, and 90% occlusion.Key FindingsPost-processing revealed 2D distributions of pressure and velocity, along with pathline and vector visualizations. Velocity contours demonstrate peak values precisely at the stenotic throat, where the flow cross-sectional area reaches its minimum.Pressure distributions show a decline in fluid pressure downstream of the stenosis, with values dropping below the inlet branch pressures.Graphical analysis of pressure, velocity, and pressure differential versus stenosis severity reveals that increasing occlusion percentage correlates with greater pressure losses and elevated blood velocities through the constricted zone, directly attributable to the enhanced flow obstruction.

DescriptionThis project simulates airflow and natural ventilation in an octagonal windcatcher using ANSYS Fluent. Windcatchers are tall rooftop towers that capture ambient wind to flush out warm, polluted indoor air and drive fresh air into the building. Their internal walls and channels trap and guide the flow downward from upper intake panels into the occupied space below. The windcatcher sits in a large open-domain environment with a horizontal wind of 10 m/s at atmospheric pressure.The geometry is created in ANSYS DesignModeler and meshed in ANSYS Meshing with an unstructured grid of 2,332,185 cells.MethodThis is a fluid-only analysis (no heat transfer). The internal layout above the windcatcher includes barrier surfaces so that some upper inlets face the wind directly while others are shielded. This arrangement establishes a pressure differential: windward openings promote inflow/traction, while leeward sides promote suction, driving circulation through the windcatcher shaft and the room beneath.ResultsPost-processing provides velocity and pressure contours, plus velocity vectors and pathlines. The windward side of the windcatcher shows higher pressure than the leeward side. Flow visualizations confirm that air enters via the top panels, is guided and trapped by interior walls, then descends and discharges through lower panels into the interior—indicating the windcatcher operates as intended.

DescriptionThis project uses ANSYS Fluent to simulate wind flow through a domain containing three buildings that act as flow barriers—representative of common “flow-around-obstacle” problems (e.g., buildings, wings, propellers, rigs). A horizontal airstream of 5 m/s enters the domain and interacts with the buildings to examine wake development and vortex behavior.Wind MethodologyThe analysis is transient over 1 s with a 0.01 s time step, solved with a pressure-based approach. The 3D geometry (DesignModeler) is a large rectangular region of 120 m × 300 m × 100 m containing three buildings, each 75 m tall. Meshing (ANSYS Meshing) is unstructured with 128,893 elements, with local refinement near building surfaces for accuracy.Wind ConclusionResults include pressure and velocity contours, turbulent kinetic energy (TKE), pathlines, and velocity vectors. The highest pressure occurs on the windward faces where the flow first impinges. Vortices form in the leeward wakes of the buildings. All reported fields are evaluated at the final simulation time (t = 1 s).

What You'll BuildThis lesson walks you through a CFD simulation of Steam Methane Reforming (SMR) — the most widely used industrial process for producing hydrogen from hydrocarbon fuels. In an SMR plant, methane reacts with steam over a catalyst to produce hydrogen, carbon monoxide, and carbon dioxide through a set of endothermic reactions, with the required heat supplied by a burner in a surrounding heating chamber.In this project, you'll model a sleeve-type SMR reactor, capturing both the catalytic reforming reactions inside the tubes and the combustion that supplies their heat — a genuinely multi-physics chemical engineering problem.What You'll LearnThe chemistry behind Steam Methane Reforming and why it's central to hydrogen productionHow to design an SMR plant geometry — heating chamber plus reforming tubes — in Design ModelerHow to generate a large unstructured mesh (~1.65 million elements) for a complex multi-zone reactorHow to set up the Species Transport model to track multiple chemical species (H₂, CO, CO₂, CH₄, O₂)How to define multiple volumetric reactions — three reforming reactions inside the tubes and one combustion reaction in the thermal chamberHow to model a porous medium as a catalyst inside the reforming tubes, coupling reacting flow with porous-zone behaviorHow to handle endothermic reactions and the heat coupling between the burner and the reforming tubesHow to post-process mass fraction contours of each species to verify methane consumption and hydrogen productionHow to interpret results to confirm the reactor is operating correctlyWhy It MattersHydrogen is central to clean energy, ammonia synthesis, and refining.

Steam Ejector — ANSYS Fluent CFD SimulationDescriptionThis project presents a CFD simulation of a steam ejector — a mechanical device with no moving parts that uses a primary (motive) steam jet to suck in and mix with a secondary fluid. Ejectors perform two essential jobs: creating vacuum for suction and mixing two fluid streams, and they do it by continuously converting between kinetic and pressure energy as the flow passes through a convergent-divergent nozzle. In this project, you'll model water vapor as the motive fluid driving the suction of a secondary fluid, watching the flow accelerate beyond the speed of sound and observing how the vacuum-driven suction physically arises. Within the Compressible Flow: Beginner CFD Training Package, this project applies convergent-divergent nozzle physics to a real industrial device, showing how supersonic internal flow generates suction and mixing.MethodologyThe 2D convergent-divergent (de Laval) nozzle ejector geometry is designed in Design Modeler and meshed in ANSYS Meshing with an efficient structured grid of roughly 52,000 elements suited to internal compressible flow. Because supersonic flow is fundamentally compressible — with density varying strongly with pressure — the density-based solver is used, the correct choice for this class of problem, and the Mach number governs the behavior inside the device. The setup handles the pressure difference between the primary and secondary inlets that drives the suction phenomenon, so the motive steam jet entrains and mixes with the secondary fluid as it accelerates through the nozzle.AnalysisPost-processing focuses on pressure, velocity, and Mach number contours, tracing where the flow goes subsonic, sonic, and supersonic through the device. From these you can follow how the motive and secondary streams mix and compress downstream of the nozzle throat, and how the vacuum-driven suction arises from the energy conversion in the convergent-divergent passage. Ejectors appear throughout refrigeration, vacuum systems, desalination, chemical processing, and power plants, and the skills built here carry directly into nozzles, diffusers, supersonic airfoils, and any flow where Mach number matters. By the end of this project, you'll be able to set up an internal compressible-flow simulation with the density-based solver, handle the inlet pressure difference that drives ejector suction, and interpret the pressure, velocity, and Mach fields that trace the subsonic-to-supersonic behavior inside the device.

DescriptionThis project uses ANSYS Fluent to simulate counterflow in a canal and analyze the resulting fluid behavior. The setup features a main water stream moving along the canal while a second stream is injected in the opposite direction from a floor-mounted pipe.The 3D geometry (DesignModeler) represents a straight channel 8 m long with a 3 m × 1 m rectangular cross-section. A 4 m long pipe of 0.05 m diameter lies along the canal floor. Meshing (ANSYS Meshing) yields 256,899 elements. A transient solver is used.Counterflow MethodologyThe main channel inflow velocity is 0.3 m/s, while the pipe issues flow at 2 m/s in the opposite direction. The region above the water surface is open to air; a pressure inlet boundary with 0 Pa gauge represents ambient conditions.Because both water and air are present, a VOF multiphase model is employed, with the standard k–ε model for turbulence.ConclusionPost-processing provides 2D and 3D fields of pressure, velocity, and phase volume fraction for water and air. The opposing jet perturbs the free surface and entrains air, producing zones with a locally reduced water volume fraction where the counterflow interacts with the main stream.

Nanofluid in a Heat Source Channel (Mixture Multiphase) — ANSYS Fluent CFD SimulationDescriptionThis project presents a CFD simulation of nanofluid cooling in a heated channel — a cutting-edge approach to thermal management in electronics, heat exchangers, and compact cooling systems. Nanofluids are engineered fluids in which nanoscale solid particles (here, aluminum oxide) are suspended in a base liquid (water) to dramatically improve thermal conductivity and heat transfer. In this project, you'll model flow through a square channel packed with ten obstacle assemblies (diagonal barriers plus a central cylinder) sitting on a solid aluminum block heated by a constant flux of 170,000 W/m². You'll run the simulation in two stages — pure water, then nanofluid — and compare the cooling performance directly. Within the Nanofluid: Beginner CFD Training Package, this project introduces the core nanofluid heat-transfer setup with the mixture multiphase model, establishing the foundation the later heat-exchanger and field-effect cases build on.MethodologyThe 3D obstacle-filled channel, mounted on a solid heated base, is designed in Design Modeler and meshed with a fine unstructured grid of roughly 2.16 million elements for the geometrically complex flow path. The Al₂O₃ nanoparticle material properties are defined — density, specific heat, thermal conductivity, viscosity, particle diameter, and molecular weight. The Mixture multiphase model is used, the correct choice when solid particles mix into a fluid without a sharp interface. Conjugate heat transfer between the solid aluminum block and the flowing fluid is modeled through a constant heat-flux boundary. The study is run as a two-step comparison: single-phase pure water versus two-phase nanofluid at a 0.01 nanoparticle volume fraction, so the cooling performance of the two can be compared directly.AnalysisPost-processing produces mixture pressure, temperature, and phase-velocity contours on the X-Z and Y-Z planes, revealing how the nanofluid moves through the obstacle-filled channel and removes heat from the aluminum block. Comparing the two stages quantifies the heat-transfer enhancement the nanoparticles provide over pure water. Nanofluid cooling is at the frontier of electronics thermal management, solar collectors, and high-performance heat exchangers, and the Mixture-model + conjugate-heat-transfer workflow built here is directly applicable to any advanced cooling design. By the end of this project, you'll be able to define nanoparticle material properties, set up the Mixture multiphase model, couple conjugate heat transfer through a heated solid, run a single-phase-versus-nanofluid comparison study, and interpret the results to quantify the heat-transfer enhancement nanofluids provide.

What You'll BuildThis lesson walks you through a CFD simulation of two-phase non-Newtonian flow between two concentric cylinders — a benchmark geometry used across drilling engineering, polymer processing, biomedical devices, and food technology. Unlike Newtonian fluids (water, air), non-Newtonian fluids change their viscosity in response to applied shear — and capturing that behavior correctly is critical for accurate predictions.In this project, you'll model a Power-Law non-Newtonian base fluid (k = 0.021, n = 0.75) flowing through an annular channel with a rotating inner cylinder, while a denser soluble secondary phase travels through it using the Eulerian multiphase model.What You'll LearnThe difference between Newtonian and non-Newtonian fluids, and when each model appliesHow to design a 3-D annular geometry (1 m length, 0.0225 m inner diameter, 0.03125 m outer diameter) in Design ModelerHow to generate a structured mesh (~1.4 million elements) appropriate for annular and rotating-flow problemsHow to configure the Power-Law viscosity model in Fluent — setting consistency index k, flow behavior index n, and clamping minimum/maximum viscosity boundsHow to set up the Eulerian multiphase model with two implicit phases, including phase-specific densities, viscosities, and inlet volume fractionsHow to apply a rotating wall boundary condition (100 rpm on the inner cylinder) — essential for any Taylor–Couette-type analysisHow to choose Coupled pressure–velocity coupling with PRESTO! pressure discretization for rotating multiphase flowsHow to post-process 2-D and 3-D contours of pressure, velocity, and volume fraction for both phasesWhy It MattersThe same workflow underpins drilling mud analysis, polymer extrusion, blood flow in narrow vessels, paint coating, and food processing — anywhere viscosity isn't constant. Mastering this case unlocks a wide family of rheologically complex industrial problems.

What You'll BuildThis lesson walks you through a CFD simulation of short waves on the sea surface — a fundamental problem in coastal, marine, and offshore engineering. Using ANSYS Fluent's ability to generate waves directly at a boundary, you'll create a realistic propagating wave field and track how the air–water interface evolves over time, all based on First-Order Airy (linear) wave theory.This is your introduction to wave generation in CFD, a capability that underpins the design of breakwaters, offshore platforms, ships, and coastal structures.What You'll LearnThe basics of First-Order Airy wave theory and how it's applied inside FluentHow to design a 2-D sea domain (210 cm long × 76 cm high) in SpaceClaimHow to generate an unstructured mesh (~55,000 cells) suited to free-surface wave trackingHow to set up the VOF multiphase model with air and water phases, sharp interface modeling, and explicit formulation with implicit body forceHow to apply the open-channel wave boundary condition to send waves into the domain from the inletWhy a transient, pressure-based solver with the laminar viscous model is appropriate for this wave problemHow to configure adaptive time stepping for stable, efficient wave propagationHow to use PRESTO! pressure discretization and Compressive volume-fraction discretization to keep the interface sharpHow to patch the initial water region and post-process velocity contours, observing how moving waves induce vortices and turbulence in the air above the surfaceWhy It MattersWave modeling is essential across naval architecture, coastal protection, renewable wave energy, and offshore oil and gas. The open-channel wave boundary condition you master here is the gateway to simulating realistic ocean environments — from ship seakeeping to wave-structure interaction.

What You'll BuildThis lesson walks you through a CFD simulation of a TNT explosion — a problem central to engineering safety, military applications, structural protection, and blast planning. An explosion is a very fast exothermic reaction that suddenly produces large volumes of hot gaseous products, spiking pressure and temperature and launching compression waves that travel outward through the surrounding air.In this project, you'll model the rapid decomposition of TNT — where 2 moles of TNT generate 22 moles of gaseous products — and watch the resulting spherical pressure wave propagate and dissipate across the domain.What You'll LearnThe physics of an explosion: fast exothermic reaction, sudden pressure rise, and the sequence of compression and expansion wavesHow to set up a half-sphere domain (5 m radius) with a central TNT charge (5 cm radius half-sphere) in SpaceClaim, using symmetry to reduce costHow to generate a large structured mesh (~2.67 million elements) capable of resolving a traveling waveWhy this problem requires a transient solver to capture moving pressure wavesHow to set up the Species Transport model with a defined species mixture and volume reactionHow to configure finite-rate turbulence–chemistry interaction and the direct source chemistry solverHow to apply the k-ε Realizable turbulence model with the energy equation activatedA critical modeling choice: defining the mixture density as an ideal gas so the simulation can capture wave travelHow to post-process temperature and pressure contours over time, plus an animation of the propagating compression wave, and quantify the wave speed (~420 m/s)Why It MattersBlast modeling protects buildings, vehicles, and people. The reacting-flow + ideal-gas + transient workflow you build here transfers directly to detonations, deflagrations, gas explosions, and pressure-vessel safety analysis across defense, oil and gas, and process industries.

What You'll BuildThis lesson walks you through one of the most fundamental and important comparisons in all of CFD: laminar versus turbulent flow inside a pipe. Rather than simulating a single case, you'll run the same geometry three times — once as laminar flow, once with the k-ε RNG turbulence model, and once with the k-ω standard model — and compare the results side by side.Understanding when a flow is laminar (smooth, ordered layers) versus turbulent (chaotic, vortex-dominated), and which turbulence model to apply, is the single most important modeling decision in CFD. This lesson gives you that intuition directly.What You'll LearnThe physical difference between laminar and turbulent flow, and how Reynolds number vs. critical Reynolds number determines the regimeHow inlet velocity drives Reynolds number — using 0.0176 m/s for laminar and 0.334 m/s for turbulent casesHow to design a symmetric 3-D half-pipe geometry (semi-cylinder, radius 0.015 m, length 1 m) in Design Modeler to cut computation in halfHow to generate an efficient structured mesh (~23,120 elements)When to choose k-ε RNG (curved geometries, transient flows, HVAC problems) versus k-ω standard (adverse pressure gradients, separation, swirling flows, aerodynamics)How to set up a pressure-based steady solver with SIMPLE coupling and second-order discretizationHow to post-process and compare pressure, velocity, and turbulent kinetic energy contours across all three regimes on the pipe's symmetry planeHow to extract velocity and pressure plots along the central axis to quantify the differences between the two turbulence modelsWhy It MattersEvery CFD engineer must answer "is my flow laminar or turbulent, and which model do I use?" on every project. This lesson builds that judgment from the ground up — making it one of the most valuable foundational skills in your entire CFD journey.

Plate Silencer and Sound Absorption — ANSYS Fluent CFD SimulationDescriptionThis project presents a CFD simulation of a plate silencer — a device used to absorb unwanted noise across industries from automotive and power generation to mining, subway tunnels, and architectural acoustics. A silencer works by vibrating in response to incoming sound waves; when the silencer's mode shapes match the sound waves, the energy is absorbed, quieting the environment. In this project, you'll model a symmetric silencer with a sinusoidal wavy plate at its center and study how acoustic waves behave as they travel through it, quantifying the silencer's noise-reduction efficiency. Within the Acoustics: Beginner CFD Training Package, this project applies the FW-H model taught earlier to a real noise-control device, opening the applied silencer and sound-absorption cases.MethodologyThe 2D symmetric silencer geometry, with a wavy central plate of 0.015 m wave amplitude, is designed in Design Modeler and meshed with a structured grid of roughly 17,000 elements for the acoustic domain. The Ffowcs-Williams & Hawkings (FW-H) acoustic model is set up, defining the far-field density (1.225 kg/m³), sound speed (340 m/s), and reference acoustic pressure (2×10⁻⁵ Pa), with acoustic sources defined near the inlet to introduce the pressure waves. The simulation must be transient to capture the wave behavior over time. The boundary conditions include a velocity inlet, a pressure outlet, and convective walls with a heat-transfer coefficient, and the setup uses the Realizable k-ε model with enhanced wall treatment and the energy equation.AnalysisPost-processing produces pressure, velocity, and temperature contours, along with Sound Pressure Level (dB) versus frequency at inlet and outlet receivers and — most importantly — the Transmission Loss diagram, which quantifies how much sound the silencer removes across the frequency range. From these results you can evaluate the silencer's noise-reduction efficiency and understand how the wavy plate absorbs acoustic energy. Noise control is a regulated requirement across the automotive, HVAC, power, and building industries, and the FW-H acoustic workflow built here is the foundation for designing mufflers, exhaust systems, and any noise-attenuating device. By the end of this project, you'll be able to set up a transient FW-H acoustic simulation of a silencer, define acoustic sources and receivers, and interpret the sound-pressure and transmission-loss results that measure noise-reduction performance.

Methane Combustion in a Gas Stove — ANSYS Fluent CFD SimulationDescriptionThis project presents a CFD simulation of methane combustion in a gas stove — a familiar everyday device that's surprisingly rich in physics. Modeling stove combustion matters for design, optimization, safety, and efficiency. As methane burns, it raises the local temperature, which lowers the air density; the hot exhaust then rises by buoyancy, drawing fresh, denser air in to sustain the flame. In this project, you'll capture that complete cycle — combustion, heat release, and natural-draft airflow — in a full 3D model. As the opening project of the Combustion: Beginner CFD Training Package, it introduces the foundational combustion workflow through the most familiar everyday burning device.MethodologyThe 3D gas stove geometry is designed in Design Modeler and meshed with a large unstructured grid of roughly 5.53 million elements using Fluent Meshing. The energy equation is activated for the reacting, heat-releasing flow, and the Species Transport model is set up with a methane combustion mechanism. The turbulence–chemistry interaction is handled with the eddy-dissipation model — a robust, efficient choice for combustion — and turbulence is modeled with the Realizable k-ε model, which offers good accuracy at low computational cost for this kind of problem. A Pressure Inlet boundary condition is applied so that the combustion air is drawn in naturally by the pressure difference rather than forced, capturing the coupled physics of combustion and buoyancy-driven natural convection.AnalysisPost-processing produces temperature, CO₂ mass fraction, and velocity contours in both 2D axial planes and 3D, revealing the flame structure, the products of combustion, and the natural-draft airflow. The results identify a peak flame temperature of about 1709 K and a buoyancy-driven velocity of about 1.33 m/s, confirming how the heat release sets up the rising exhaust and the fresh-air intake that sustains the flame. Combustion plus natural draft appears in stoves, furnaces, water heaters, flares, and fired heaters, and the Species Transport + eddy-dissipation + buoyancy workflow built here is a foundational, widely transferable combustion-modeling skill. By the end of this project, you'll be able to set up a reacting-flow simulation with the Species Transport model and a methane combustion mechanism, configure the eddy-dissipation turbulence–chemistry interaction, apply a pressure-inlet natural-draft boundary condition, and interpret the temperature, species, and velocity fields of a buoyancy-driven combustion problem.

What You'll BuildThis lesson walks you through a CFD simulation of a sea robot moving through water using the Dynamic Mesh technique — the essential method for problems where a body physically moves through the fluid domain and the computational cells must change shape and position over time.In this project, the robot (modeled as a cube) starts on one side of the domain and travels toward the inlet against an oncoming water stream, letting you study the pressure buildup ahead of it and the wake region trailing behind.What You'll LearnWhen and why a Dynamic Mesh is mandatory — whenever the location or shape of computational cells changes during the simulationHow smoothing and remeshing work together to maintain high-quality elements as the body moves, preventing the mesh degradation that causes solver errorsHow to configure remeshing intervals (here, every 50 iterations) to regenerate a fresh, high-quality meshHow to design a 2-D moving-body domain in Design Modeler and mesh it (~30,010 elements) in ANSYS MeshingWhy a transient solver is required for any Dynamic Mesh problemHow to impose a prescribed velocity profile on the moving body (3 m/s in the X-direction over 0–3 seconds)How to set up the surrounding flow with an inlet water velocity of 1.5 m/s using the standard k-ε turbulence modelHow to post-process velocity, pressure, turbulent viscosity contours, and streamlines — observing the elevated stagnation pressure ahead of the robot and the wake region behind itWhy It MattersDynamic Mesh is the gateway to simulating real motion — submarines, AUVs, valves, pistons, projectiles, and store separation.

Fan Stage (Axial Flow) Aerodynamic Performance — ANSYS Fluent CFD SimulationDescriptionThis project presents a CFD simulation of an axial flow fan stage — a rotor–stator assembly that produces steady airflow for industrial applications such as cooling freshly painted body parts. The rotor's spinning blades accelerate the incoming air and induce swirl, and the stationary stator blades then straighten the flow so it exits roughly normal to the outlet. This is a classic, approachable introduction to turbomachinery CFD, and in this project you'll model both the rotating and stationary zones and evaluate the fan stage's aerodynamic performance. As the opening project of the Fan: Beginner CFD Training Package, it introduces the fan itself — its aerodynamics and the MRF rotating-zone method — establishing the foundation the fan-driven HVAC and ventilation cases build on.MethodologyThe 3D rotor–stator geometry is designed in Design Modeler with separate rotating and stationary zones defined, then meshed in ANSYS Meshing with roughly 244,675 cells. A periodic boundary condition is used to model only a slice of the fan rather than the full annulus, dramatically reducing computational cost. The MRF (Moving Reference Frame) method is set up to simulate the rotor's rotation at 1800 rpm while keeping the stator fixed — a steady-state approach that avoids the expense of a fully transient moving mesh — and the standard k-ε turbulence model is applied to the rotating flow field.AnalysisPost-processing produces 2D and 3D pressure, velocity, streamline, and velocity-vector results, clearly visualizing the swirl induced by the rotor and its correction by the stator. From these you calculate the key turbomachinery performance metrics: a rotor tip linear velocity of about 31 m/s, a Tip Speed Ratio (TSR) of 4, and an outlet airflow rate of 16.14 lit/s. Fans, compressors, pumps, and turbines all rely on rotor–stator interaction, and the MRF + periodic-boundary workflow learned here is the standard, cost-efficient approach to turbomachinery analysis — directly transferable to blowers, axial compressors, and ventilation fans. By the end of this project, you'll be able to build a rotor–stator geometry with distinct motion zones, apply periodic boundaries to model a representative slice, set up the MRF method for a rotating fan, and post-process the flow to compute the performance metrics that define fan behavior.

DescriptionIn this project, we present a simulation of an Airfoil exposed to the airflow via ANSYS Fluent software.Since the airfoil is exposed to airflow, an interaction occurs between the wind blowing and the airfoil structure. It means that airflow exerts a volume force on the airfoil's body by hitting it. Therefore, we intend to perform a numerical simulation of the airfoil as a Fluid-Structure Interaction (called FSI).The interaction between fluid and structure can be implemented as:One-way FSITwo-way FSIIn this project, we aim to analyze only the effect of fluid on the structure, and there is no need to account for the effect of the structure on the fluid. So, we choose One-way FSI, which is a simple and less-expensive approach.We modeled the geometry via SpaceClaim software. The computational domain is a sample space of the surrounding air that includes both fluid and solid domains. There is a solid airfoil structure within the fluid environment, which is considered fixed from the center.We meshed the computational domain via ANSYS Meshing software. The mesh is of an unstructured type, and approximately 1,700,000 cells have been generated.MethodologyFluid-structure interaction can be performed in two general methodologies:In the ANSYS Workbench environment, using an external solver (specifically, system coupling)Only in the Fluent solver (in the form of an intrinsic FSI).In this project, we implemented a one-way FSI in the ANSYS Fluent environment. In other words, the Fluent solver performs both fluid and solid calculations simultaneously.For two-way FSI in Fluent solver, the Structure model is utilized. The structural model can be implemented in two ways:Linear elasticity: The deformation is proportional to the applied force. In this case, the deformations are usually small, and the calculation process is faster.Nonlinear elasticity: The deformation is not necessarily proportional to the applied force. In this case, the deformations are usually large, and the calculation process is more complex and time-consuming.In this project, we considered fluid-structure interaction in the form of a Linear Elasticity state.Since we were analyzing one-way FSI and not considering the effect of structural displacement on the adjacent fluid, we didn't need to use the dynamic mesh model.ResultsWe analyzed the results in two fluid and solid approaches:In a fluid view, we studied the behavior of airflow. For this, we obtained the distributions of the pressure and velocity of air. The results show that the airflow collides with the airfoil body at high speed and, as a result, exerts a hydraulic force on the airfoil structure.In a solid view, we studied the behavior of the airfoil body under the influence of the applied forces of the air flow. For this, we obtained the distribution of the von Mises stress and displacements (in all directions). The results confirm that the airflow affects the airfoil structure and, as a result, it undergoes displacements relative to the fixed center.In conclusion, we can claim that we carried out the simulation project of an airfoil correctly and acceptably by using the two-way FSI method.

Water Jet Considering Cavitation — ANSYS Fluent CFD SimulationDescriptionThis project presents a CFD simulation of cavitation inside a water jet — a device that produces a thin, ultra-high-speed water stream (often mixed with an abrasive) to cut or clean hard materials. As water accelerates through the jet, the pressure can fall to its vapor pressure, triggering cavitation: the local formation of vapor bubbles within the liquid. Capturing this phenomenon is essential, because cavitation drives erosion, noise, and performance loss in many fluid devices. In this project, you'll model the phase change between water and vapor and study how the vapor region forms and grows. Within the Mass Transfer: Beginner CFD Training Package, this project introduces cavitation as a pressure-driven phase change, extending the mass-transfer methods from temperature-driven boiling and condensation to a phenomenon governed by pressure.MethodologyThe 2D water jet geometry is designed in Design Modeler and meshed with a structured grid of roughly 57,018 elements for the internal nozzle flow. The VOF multiphase model is set up with water and vapor phases using sharp interface modeling and an implicit formulation, and the cavitation mass-transfer mechanism is activated between the two phases with a defined vapor pressure of 3540 Pa. The boundary conditions are a velocity inlet (10 m/s, pure water) and a pressure outlet. Coupled pressure–velocity coupling is chosen with PRESTO! pressure and Compressive volume-fraction discretization for the cavitating flow, and the k-ε RNG turbulence model with standard wall functions is applied.AnalysisPost-processing produces pressure, velocity, water volume fraction, and vapor volume fraction contours, used to locate where cavitation begins. The results show the pressure falling as the water accelerates through the jet, and where it reaches the vapor pressure, vapor forms — visible in the vapor volume-fraction field as the cavitation region taking shape. From these you can identify exactly where cavitation initiates and how the vapor region grows. Cavitation is a critical concern in pumps, propellers, valves, injectors, and hydraulic machinery, and the VOF + cavitation mass-transfer workflow built here transfers directly to predicting and mitigating cavitation damage across countless fluid systems. By the end of this project, you'll be able to set up a VOF multiphase simulation with the cavitation mass-transfer mechanism, define the vapor pressure that triggers phase change, configure the solver and discretization for cavitating flow, and interpret the pressure and vapor-fraction fields that reveal where cavitation occurs.

Magnetic Force Effect on an Airfoil — ANSYS Fluent CFD SimulationDescriptionThis project presents a CFD simulation of the Magneto-Hydro-Dynamic (MHD) effect on a NACA 0015 airfoil — an example of active flow control, where an external field is used to manipulate the flow and improve aerodynamic performance. The NACA 0015 is a symmetric airfoil that produces no lift at zero angle of attack, making it an ideal baseline for isolating the influence of the magnetic force. In this project, you'll investigate flow separation and stall, then apply a magnetic force to see how it delays separation and boosts lift. Within the Magnetohydrodynamics & Electrohydrodynamics (MHD & EHD): All Levels CFD Training Package, this project applies the magnetic field effect to an external aerodynamic body, building on the fundamental MHD flow case toward active flow control on a lifting surface.MethodologyThe 2D airfoil geometry is designed in Design Modeler and meshed in ANSYS Meshing with an unstructured triangular mesh around the airfoil. The MHD module in ANSYS Fluent is enabled and configured to apply a magnetic force to the flow — a magnetic body force that acts on the boundary layer. The study is set up as a comparative one: the lift coefficient is evaluated across multiple angles of attack, both with and without the MHD effect, so the influence of the magnetic force can be isolated directly. This allows the flow separation point and the maximum angle of attack before separation to be identified in each case.AnalysisPost-processing produces velocity and pressure contours, streamlines, and velocity vectors that visualize the boundary-layer energizing and the increased leading-edge suction. The comparative study demonstrates that the magnetic force accelerates the boundary-layer flow, keeping it attached to the surface and delaying stall to a larger angle of attack — raising the lift coefficient relative to the case without MHD. From these results you can see exactly how the magnetic body force controls separation and improves aerodynamic performance. Active flow control via MHD and plasma actuators is a frontier topic in aerospace and energy, and the MHD-module workflow learned here applies to lift enhancement, drag reduction, stall delay, and flow-control research across aircraft, turbines, and high-speed vehicles. By the end of this project, you'll be able to enable and configure the MHD module in ANSYS Fluent, apply a magnetic body force to a flow, run a comparative lift study across angles of attack, and interpret the velocity and pressure fields that reveal how the field delays separation and enhances lift.

Helicopter Rotor (Mesh Motion) — ANSYS Fluent CFD SimulationDescriptionThis project presents a CFD simulation of rotating helicopter rotor blades using the Mesh Motion technique in a transient formulation. A helicopter stays aloft by forcing a large mass of air downward through its rotating blades, generating an equal and opposite upward force. By aerodynamically shaping the blades and spinning them, the rotor raises the air pressure beneath the wing and creates lift. In this project, you'll model that rotating rotor and quantify the net upward force, blade tip speed, and Tip Speed Ratio. Within the Mesh Motion: Beginner CFD Training Package, this project extends the rotating-zone method from the aircraft propeller to a helicopter rotor, applying it to rotorcraft lift generation.MethodologyThe 3D rotor and surrounding domain are designed in Design Modeler and meshed in ANSYS Meshing with roughly 937,677 elements. The rotor is made up of two or more wing-shaped blades, which generate a pressure difference across the blade as they spin. The Mesh Motion method is used to simulate the continuous blade rotation at 1250 rpm about the Y-axis, and a transient solver is required to capture the rotating motion over time. The RNG k-ε turbulence model is applied for the rotating flow field, resolving the swirling air motion the blades induce.AnalysisPost-processing produces velocity, pressure, and turbulent-viscosity contours along with streamlines, revealing the swirling air motion induced by the blades. From these, the key performance metrics are extracted: the pressure difference across the rotor (5 Pa), the maximum domain air velocity (2 m/s), and the blade tip velocity (1.96 m/s) — the quantities that characterize the rotor's ability to generate lift. Mesh Motion is a core technique for any continuously rotating machinery analyzed in transient mode — helicopter rotors, propellers, wind turbines, and mixers — and the rotating-flow workflow built here gives you a foundation for rotorcraft aerodynamics and rotating-blade performance studies. By the end of this project, you'll be able to set up a transient Mesh Motion simulation of a rotor, define continuous blade rotation about an axis, apply the RNG k-ε model to the rotating flow, and interpret the pressure and velocity fields and performance metrics that describe helicopter lift.

DescriptionThis project simulates airflow over a dimpled rotating cylinder using ANSYS Fluent software. A cylindrical object is placed inside a rectangular channel. The airflow enters the channel at a horizontal velocity of 0.45 m/s and collides with the cylindrical body.The cylinder rotates about its central axis at an angular velocity of 20 radians per second (rad/s), so a moving wall must be defined. For this reason, the fluid simulation domain is divided into two parts: the rotating region, which contains the cylinder rotating at a constant angular velocity, and the surrounding fluid region, which is the interior of the rectangular channel outside the cylinder.The cylinder wall features dimples whose protruding side faces the inside of the cylinder and whose recessed side faces the outside. The aim of the study is to investigate the pressure distribution and the rotational phenomena around the rotating cylindrical wall, since the presence of dimples on the cylinder surface influences the behavior of the fluid.The geometry of the present model is three-dimensional and is designed using SOLIDWORKS software. The meshing is performed with ANSYS Meshing software. The mesh type is unstructured, and the number of elements is equal to 1,064,903.Dimpled MethodologyA cylindrical wall is created in the form of an interface, that is, a common surface shared between two regions that allows the fluid to flow across its boundary. Around this wall, a dedicated flow region in the shape of a hollow cylinder is defined to represent the rotating cylinder. The Frame Motion (MRF) method is then used to simulate this inner cylindrical region, which rotates at the same angular velocity as the main cylinder.Dimpled ConclusionAt the end of the solution process, contours of pressure, velocity, and turbulent kinetic energy are obtained. Using the MRF method, the cylinder can be assumed stationary while the surrounding airflow is treated as rotating at the same rotational speed of 20 rad/s around the central axis of the cylinder. The contours clearly show the velocity and pressure distributions within the domain.

Solar Radiation Effect on a Gasoline Tank — ANSYS Fluent CFD SimulationDescriptionThis project presents a CFD simulation of solar radiation heating a gasoline tank — an important safety and storage problem, since overheating fuel raises vapor pressure and evaporation risk. Using ANSYS Fluent's radiation modeling, you'll capture how sunlight heats the tank and its contents, and how a protective coating can mitigate that effect. In this project, you'll model a cylindrical fuel tank in an external airflow and run a comparative study — with and without an insulating coating layer. As the opening project of the Radiation: Beginner CFD Training Package, it introduces the radiation and solar-load workflow on the simplest case — a single object under the sun — establishing the foundation the building and HVAC cases build on.MethodologyThe 3D cylindrical gasoline tank is designed inside an external flow domain in Design Modeler and meshed in ANSYS Meshing with an unstructured grid of roughly 1,084,362 cells. The P1 radiation model is set up — well suited to this case for its low CPU cost and its handling of scattering and optically thick media — and solar ray tracing and the Solar Load model are activated to apply realistic thermal loading from the sun.

Manifold of Engine (Species Transport) — ANSYS Fluent CFD SimulationDescriptionThis project presents a CFD simulation of air–fuel mixing in an engine manifold using the Species Transport model without chemical reactions. The manifold has two inlets — one supplying air, one supplying a multi-component fuel gas — and three outlets, of which only one is open while the other two are blocked (treated as walls). The goal is to study how the species mix as they travel through the manifold and to evaluate the pressure on the blocked surfaces. As the opening project of the Species Transport: Beginner CFD Training Package, it introduces the model in its simplest form — tracking and mixing multiple species without chemistry — establishing the foundation the dispersion and reacting-flow cases build on.MethodologyThe three-outlet manifold fluid domain is designed in Design Modeler and meshed in ANSYS Meshing with an unstructured grid of roughly 231,646 elements. A multi-species mixture is built from the Fluent database (N₂, O₂, CO₂, CO, H₂, CH₄, H₂O), and the energy equation is activated along with the inlet diffusion and diffusion energy source options. Species mass fractions are set at each inlet — air (N₂ 0.79, O₂ 0.21) and a multi-component fuel stream (CO, CH₄, CO₂, N₂, H₂). Mass-flow inlet boundary conditions are applied — air at 0.2335 kg/s and fuel at 0.0374 kg/s — with the blocked outlets modeled as walls. The k-ε Standard model with enhanced wall treatment is used, together with PISO pressure–velocity coupling. Crucially, the Species Transport model here tracks how the multiple gas species convect, diffuse, and mix without any combustion reaction.AnalysisPost-processing examines the species distributions through the manifold, showing how the air and fuel streams mix as they travel toward the open outlet, and evaluates the outlet mixture mass flow rate (0.271 kg/s) and the pressure on the blocked outlet surfaces (771.45 Pa and 780.98 Pa). From these results you can assess the quality of the mixing and the loading on the closed surfaces. Species Transport without reactions is the foundation for mixing, intake, dilution, and ventilation analysis, and mastering multi-species mixtures and mass-fraction boundary conditions here prepares you for combustion, emissions, and any flow where gas composition matters. By the end of this project, you'll be able to build a multi-species mixture, set species mass-fraction inlet conditions, run a non-reacting Species Transport simulation, and interpret the concentration, mass-flow, and pressure results that characterize gas mixing in a manifold.
