Abstract

With high-speed automobiles much more common nowadays, reducing the lift coefficient to enhance stability on the road is no longer just a concern for race cars. Spoilers are one of the well-known devices for producing down force on a moving vehicle. However, sometimes the spoilers are known as devices which increase the drag coefficient. The aim of this study was to design a spoiler that both reduce lift and drag forces. This study investigates the effect of numerous rear-spoiler's angle on lift and drag coefficients of the models. We obtained significant reduction of lift and drag forces of the models. The popular k-ω SST turbulence model was used to assess aerodynamic forces, as well as pressure and velocity distribution. This study provides a good comparison between different angles of spoilers, making it easier to determine an optimum model.
