Influence of different angle of spoiler fin at specific position on vehicle aerodynamics

Abstract


The significance of Aerodynamic Research on automobile is not only to improve the high-speed driving stability and crosswind stability, but also to reduce vehicle fuel consumption. As an additional device, the rear spoiler has shown a good effect in the external components of the automobile, so the reasonable design and assembly of the rear spoiler is particularly important. The rear spoiler with proper height can effectively reduce the air drag coefficient and lift coefficient. This paper mainly uses the software ICEM, Fluent and Post in ANSYS to analyze the influence of different angles of the specific spoiler on the aerodynamic performance of the vehicle. In the software experiment, I adjusted the spoiler angle and car speed and I found that in a certain range, the downforce generated by the spoiler is proportional to the angle between the spoiler and the ground.
