Abstract

A two-dimensional and three-dimensional computational study has been carried out respectively regarding aerodynamic forces affecting a symmetric spoiler, NACA0015 and a cambered spoiler, NACA2414. The negative lift (down force) and drag forces were predicted through the simulation of airflows over inverted rear-wings (spoilers) in different configurations namely; varying incidences i.e. angles of attack of the airfoils, two dimensional cross-section of the wings, and varying speeds of initial airflow. The downforce increases as the angle of attack increases however, at high angle of attacks the rear-wing starts to stall which is not a desired condition affecting the vehicle stability. Furthermore, the camberness added to the airfoil increased the downforce, which contributes more to the stability concept of the automobile.
