Computational Fluid Dynamics Analysis of Inverted, Multi-Element Airfoils in Ground Effect
<p>Formula SAE cars are formula-styled race cars designed to race on an autocross circuit. The autocross circuit is mostly comprised of turning sections as well as a limited amount of straight sections for passing other cars. Highly competitive cars in the competition implement aerodynamic devices …
