This paper presents the optimization and aerodynamic performance of a Formula SAE vehicle nose cone. The purpose of the study is to minimize drag while simultaneously enhancing downforce to improve traction and acceleration of the vehicle. Numerous CAD models of the nose cone were developed, taking into account factors such as chassis dimensions, ground clearance, and Formula SAE rulebook constraints. Computational Fluid Dynamics (CFD) analysis is carried out in ANSYS 2021 Fluent module. The fluid domain was created and meshed using tetrahedral cells, and the flow field was predicted using the Realizable k-ε turbulence model. The simulation results revealed essential information including drag and lift coefficients, as well as pressure and velocity contours. An in-depth analysis of lift and drag coefficients guided the optimization of the nose cone design. The study ultimately identified a nose cone design that yielded the most favorable drag coefficient and is found in the range between 0.2-0.3. The study also observed that the down force is increased by 27%. This design proved highly effective in reducing the vehicle's drag and sufficient downforce to enhance acceleration.
