Study of Aerodynamic Drag Reduction on a Compact Electric Vehicle

Abstract:

Aerodynamic drag of compact electric vehicles is of significant interest in reducing energy consumption. This study focused on how to reduce drag for a compact electric vehicle by shape optimization such as lengthening the tail, changing the front-windshield inclination, modifying the diffuser angle and filling up the front structure details of the vehicle model. Some separately refined models and one integrated refined model were built. The simulation was conducted using the RANS k-epsilon turbulence model by Computational Fluid Dynamics. The results show that nearly every refined model has a lower drag, and the drag coefficient of the integrated refined model has an 8.4% slash compared to the original vehicle model.
