The geometry represents the meat sample and surrounding air domain, discretized with a structured mesh of 58,800 elements to accurately capture heat and mass transfer gradients. The meat drying process was simulated using CFD to analyze heat and mass transfer during drying. The VOF model was applied to capture multiphase interactions between liquid water and vapor. The meat was modeled as a porous medium to represent internal moisture transport. Infrared heating and air convection were used as drying mechanisms under two operating cases. Results showed that higher heat flux and temperature enhanced drying efficiency and reduced moisture content.

In the oscillating multiphase CFD study, the interaction of water and air inside a narrow rectangular channel is investigated using ANSYS Fluent. The geometry is created in ANSYS Design Modeler and meshed with a structured grid of 480,760 cells in ANSYS Meshing. The Volume of Fluid (VOF) method is applied for tracking the water and air interface, with water defined as the primary phase and air as the secondary phase. A dynamic mesh technique with smoothing and re-meshing options is enabled, along with a moving wall defined by a User-Defined Function (UDF).

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.

This artery flow project involves the simulation of blood flow in a compliant artery using CFD and FSI techniques in ANSYS. The primary objectives are to validate the simulation against a published study, analyze mesh independence, and investigate the effects of wall compliance and porosity on hemodynamic behavior. The artery geometry is simplified and reconstructed for numerical accuracy, with meshing performed in ANSYS Meshing and flow solved using Fluent. Wall deformation is modeled using the FSI module, while porosity effects are simulated by assigning high-viscosity fluid properties to the vessel wall. Simulations are performed under unsteady, incompressible flow conditions with non-Newtonian blood properties. Key results include time-dependent deformation, wall shear stress, and velocity distributions, with validation confirming a shear stress error below 1% in mesh studies.

The project aims to evaluate and enhance hospital room ventilation systems to effectively control aerosol dispersion, a crucial aspect of maintaining a safe environment within healthcare facilities. Three scenarios are analyzed: sneezing, coughing, and breathing, each with varying particle injection velocities and mass flow rates, to observe their effects on airflow patterns and particle trajectories. The simulation highlights that current ventilation setups exhibit limitations, as particles often become trapped or follow circular paths, indicating areas for improvement in ventilation strategy. Results suggest optimizing airflow by adjusting inlet and outlet conditions and improving flow patterns to enhance particle escape and overall air quality, ensuring safety and comfort in hospital settings.
