PBM with CFD Simulation of FeNi Nanoparticle Synthesis is performed using ANSYS Fluent . A Multiphase Eulerian approach is applied with FeNi alloy represented in the secondary phase. Powder precursors (FeCl₂ and NiCl₂) are injected into the domain using the Discrete Phase Model (DPM). The Species Transport Model with finite-rate Arrhenius kinetics is used to simulate the reduction reactions. User-Defined Functions (UDFs) implement nucleation, growth, and agglomeration phenomena for nanoparticle prediction.

In the thermal effects on mixing in pipesCFD study investigates the thermal effect on the mixing of glycerin and water in a Y-shaped pipe using ANSYS Fluent. The geometry is created in ANSYS Design Modeler and meshed in ANSYS Meshing to generate a high-quality computational grid. The Volume of Fluid (VOF) method with an implicit formulation is applied, and the realizable k–epsilon model is used for turbulence modeling. A mass flow inlet of 0.15 kg/s is set for both phases, and simulations are carried out without heat flux and with a 30,000 W heat flux.

In this project, the heat transfer performance of a shell-and-tube heat exchanger with air bubble injection was simulated using ANSYS Fluent software. Three cases were studied: air injection into the shell, into the tube, and into both sides simultaneously. The geometry was created in SpaceClaim and meshed in ANSYS Meshing, initially generating about 12.6 million tetrahedral elements, later converted to a polyhedral mesh with approximately 2.43 million cells to reduce computational cost. The model was solved using a pressure-based steady solver with gravity effects included. A VOF multiphase model was applied to track air and water phases, while the realizable k-ε turbulence model with standard wall functions was used to capture flow behavior. The energy equation was enabled, and the SIMPLE algorithm with second-order upwind discretization ensured solution accuracy.

In the Laser Cladding project, we simulated the deposition of nickel droplets under an argon gas stream using ANSYS Fluent software. The three-dimensional geometry was created in Design Modeler with a computational domain of 0.05 × 0.01 × 0.025 m. A structured non-conformal mesh was generated in ANSYS Meshing, consisting of approximately 798,400 computational cells with refined regions near the deposition zone. The transient simulation employed the VOF multiphase model, coupled with species transport and energy equations, while turbulence was modeled using the Realizable k-ε model. A User-Defined Function (UDF) implemented the moving Gaussian laser heat source, enabling realistic simulation of droplet injection, spreading, and weld layer formation.

Co-firing Biomass with Coal Gasification. This project involves the simulation of coal and biomass co-firing in a furnace using CFD techniques. The primary objectives are to examine the combustion characteristics and validate the simulation results against the study by Ghenai and Janajreh. The furnace is defined with specific boundary conditions, and simulations are performed using an unsteady, incompressible flow model. The turbulent flow within the furnace is modeled using the k-e RNG turbulent model, thermal radiation is simulated with the P1 model, and combustion is analyzed with a PDF model. The simulation incorporates the kinetics/diffusion-limited rate model for particle combustion and the two competing rates Kobayashi model for devolatilization. Results are compared in terms of temperature contours and particle trajectories, confirming the simulation’s accuracy with a maximum error of approximately 5% in particle temperature ranges.
