This project investigates the optimization of the aerodynamic design of a car rear spoiler. Several types of designs have been chosen in this project to make a comparison. A Bezier curve fitting approach is used as a tool to improve the existing design of the rear spoiler. A formal optimization technique based on computational fluid dynamics (CFD) is used to determine the control points for the approximate curve that covers the rear spoiler. It is hoped that with this analysis, the designation of the rear spoiler will be one of the factors to be considered by car users to choose their rear spoiler to reduce drag and hence improve the car’s performance.

This project investigates the optimization of the aerodynamic design of a car rear spoiler. Several types of designs have been chosen in this project to make a comparison. A Bezier curve fitting approach is used as a tool to improve the existing design of the rear spoiler. A formal optimization technique based on computational fluid dynamics (CFD) is used to determine the control points for the approximate curve that covers the rear spoiler. It is hoped that with this analysis, the designation of the rear spoiler will be one of the factors to be considered by car users to choose their rear spoiler to reduce drag and hence improve the car’s performance.
