Study of Airflow Due to Rear Diffuser of Supercar

Abstract

A supercar is one of the best categories for cars. These cars are usually the most effective of the best and are in extremely restricted quantities. Supercars are exotic cars, and that means they need a beautiful style, besides as unbelievable performance. These supercars are among the fastest and have the best sport handling in the world. Improving aerodynamic properties and a car's aerodynamic drag resistance is the easiest and most cost-efficient way to tackle this issue. A common device used to improve aerodynamics in sports cars and race cars is a diffuser which enhances the recovery of pressure. In this study, the drag-reduction effect of a diffuser on a sedan car was tested. Computational fluid dynamics (CFD) simulations were performed to understand the impact of the diffuser. For such simulations, diffusers with different angles have been checked to find the most effective drag reduction configuration. Research has shown that it is possible to improve the aerodynamic characteristics by adding diffusers at the car's underbody.
