Flow around an Ahmed Body using StarCCM+
This project deals with simulating the flow around an Ahmed Body, which is a prototypical car model. In order to perform this simulation, a computational domain will be defined in the form of a virtual wind tunnel. The simulation will be run for 25 and 35° slant angles and the flow patterns will be studied for both cases. Multiple cases for various slant angles can be run to show how the separation at the rear takes place and how the wake is affected, ultimately affecting the drag produced by the body. Finally, the results will be compared with the experimental results to get an idea of which solution and turbulence models to use and fine tune the setup to provide the best results.
