Project Objective
The aim of this project was to perform a comprehensive CFD study of the Drivaer fastback model and design a high-performance aerodynamic package. This involved optimizing key components including the rear wing, diffuser, and front splitter to maximize downforce while minimizing drag.
Methodology Overview
The project followed a systematic approach combining computational fluid dynamics (CFD) simulations with CAD design iterations. Each component was analyzed individually and then integrated into the complete vehicle package for final optimization.
