Abstract
In order to optimize the flow field at the bottom of the car body and reduce the aerodynamic resistance of the wheel, the flow field of the basic model is simulated and analyzed using the numerical simulation, and the eyebrow spoiler has been designed in this paper. The simulation results show that the drag reduction effect of the front wheel spoiler is 24 counts, and the actual drag reduction effect is 22 counts from the wind tunnel testing, which can reduce the energy consumption by 2%. Therefore, the "eyebrow" spoiler can reduce the impact of air flow on the front wheel, lead the airflow flowing smoothly, achieve high performance in drag reduction, and finally reduce energy consumption.
