Abstract
In automotive industry, selection of slant angle of a car can be aerodynamically problematic. As the simplest case, a generic Ahmed body car model is used to show the effect of slant angle on the aerodynamic outputs of the flow around it. Pressure coefficient distributions are calculated numerically and wake vortices are captured by use of a solution adaptive Cartesian grid based CFD solver. Roe’s Riemann solver is employed for iteratively simulating the flow. Multi-grid methods are implied in the flow solver for faster convergence rates. Results at 25° slant angle are compared with experimental data from literature for validation and Ansys FLUENT results for verification. As the future work, this study can be extended to solve three dimensional boundary layer interactions around the car model and experimental setup can be designed for self-validating the CFD results.
