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).

Description This 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 Methodology The 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. Conclusion Post-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.
