In order to further improve the aerodynamic performance of car spoilers, the research team adopted the idea of “movable spoiler”, a rear wing of automobiles whose angle of attack changes with different motion states of the car. Using ANSYS Fluent software to simulate parameters such as lift-to-drag ratio under different conditions, the group did analysis for four conditions: 10 m/s, 30 m/s, 50 m/s and braking, drew the data into charts and got conclusions by observing the graphs. The group also did a shape optimization for an airfoil in NACA database as further investigations
