CFD simulation showing oblique shock formation.Overview:
Computational Fluid Dynamics is a fundamental topic in engineering, allowing us to simulate real-world scenarios computationally with the help of numerical methods. This project implements a supersonic flow over a diamond-shaped airfoil surface using a 2D Euler solver with finite volume formulation.
The solver was developed in two stages:
- A first-order AUSM+up scheme
- A higher-order TVD MUSCL formulation
The solver successfully captures oblique shock waves generated at the airfoil’s leading edge and compares results (wave angle, Mach number, pressure and temperature ratios) with analytical solutions.
Results
- Solver captured leading-edge oblique shocks accurately.
- Verified wave angles and pressure ratios against analytical data.
- Demonstrated improvement moving from first-order AUSM+up to MUSCL scheme.
