Projects
These are some of the projects I have completed during my Fall 2024 semester in CFD.
In this project, I implemented a numerical solution for a two-dimensional, steady-state heat conduction problem with spatially varying thermal conductivity. The project involved discretizing the governing heat conduction equation:
The domain was rectangular, with the top section made of stainless steel. The lower section's material was varied, testing materials with thermal conductivities between 0.1 and 300 W/m²K. The objective was to assess how different conductivities impact the temperature distribution within the domain.
Temperature field for nx = 100 by ny = 100. Thermal conductivity off top and bottom material is 15 and 150 W/mK respectively.
2D Steady-State Heat Conduction Using Finite Difference Method
In this project, I implemented the Forward Euler explicit method and Backward Euler implicit method (using Gauss-Seidel as an iterative solver) for a two-dimensional, transient conduction problem with spatially varying thermal conductivity, density, and specific heat capacity. The project involved discretizing the governing heat conduction equation:
The domain was rectangular, with a triangular section made of stainless steel at the top. The lower section's material was varied, testing materials with various thermal conductivites. The objective was to assess how different conductivities impact the temperature distribution within the domain over time.

2D Transient Heat Conduction Using Finite Difference Methods
For my Final Project, I used ANSYS Fluent to solve a computational fluid dynamics problem involving heat transfer and fluid flow. The geometry consisted of a rectangular tank with a small, heated aluminum plate inside. The fluid domain was filled with water, and the flow was analyzed under varying inlet velocities and heat flux conditions. The objective was to assess how these factors influence temperature, velocity, and pressure distributions within the domain, with a focus on grid refinement, turbulence modeling, and material properties.
