Abstract
The Formula 1 race car aerodynamics has some basics objectives: the improvement of downforce, focusing on pushing the vehicle down, and the improvement of cornering forces. In this work, a numerical analysis using a simplified geometry of a Formula 1 car was performed. A virtual wind tunnel was created and simulated by using computational fluid dynamics. A mesh independence test using four spatial resolution for discretization were build and the best one was used for the numerical analysis, the criteria for mesh choose was a variation on cD less than 2.00%. The simplified geometry was analyzed by surface contributions dividing the same in several compounds. It was noticed that wheels and wind have a strong effect on drag and lift forces. The final cd obtained in this work is comparable with published data of Formula 1 cars.
