Aerodynamic enhancement of electric vehicles using a 15° straight-wing spoiler: A CFD analysis
Year: 2025
Type: article
Abstract: Electric vehicles' aerodynamic performance must be improved to increase energy economy and driving stability. This study uses Computational Fluid Dynamics (CFD) simulations to investigate how a straight-wing spoiler with a 15° inclination affects an electric vehicle's aerodynamic properties. A modified model with a spoiler and a basic model without one were compared. The findings showed an almost constant drag coefficient and a notable decrease in lift, which greatly improves vehicle stability. According to a pressure distribution study, the spoiler successfully improved traction and reduced the chance of lift-off at high speeds by increasing downforce at the back of the car. Better airflow management, less turbulence, and increased aerodynamic efficiency were all shown via streamlined analysis. These results imply that a straight-wing spoiler can improve electric vehicles' stability and aerodynamic performance without adding undue aerodynamic resistance. By offering insights into spoiler optimization, this study advances the design of electric vehicles and aids in creating more reliable and energy-efficient electric car technologies.
