Fundamentals and Application of Computational Fluid Dynamics
This first module of the CFD Master’s program laid the groundwork for applying numerical methods to fluid flow. It combined theory on the finite volume method (FVM), turbulence models, and compressible/incompressible flows with practical training in Ansys Fluent and SpaceClaim
Assignments progressively built from simple to more advanced cases:
Homework 1 – Flow over a backward-facing step: creation of geometry, meshing, and setup of periodic boundary conditions to achieve fully developed turbulent flow. Results compared k-ε and k-ω SST turbulence models, focusing on velocity profiles, reattachment length, and turbulent kinetic energy distribution.
Homework 3 – Pipe flow and turbulence onset: evaluation of laminar vs. turbulent regimes, confirming pressure losses and velocity development along the pipe.
Homework 4 – Heat transfer in internal flow: introduction of thermal boundary conditions and energy equation coupling to examine how flow affects wall temperature distribution.
Homework 5 – Mesh independence study: systematic variation of grid resolution to check solver stability and sensitivity of results, reinforcing best practices for numerical accuracy.
Homework 6 – Compressible nozzle flow: analysis of subsonic and supersonic conditions through a convergent-divergent nozzle, including shock formation and Mach number distribution.
Final Homework – Advanced backward-step study: expanded simulations with multiple inlet profiles and turbulence models, highlighting how wall treatments, friction velocity, and y⁺ scaling affect flow prediction
By the end of the module, I had a structured understanding of the CFD workflow — from geometry and meshing to solver setup, turbulence modeling, and postprocessing. This provided the foundation for all later CFD courses in the program
