Abstract
Scientists around the world have been studying for developing alternative solutions to replace fossil fuels to prevent environmental and resource problems. Electric cars are crucial in transport technologies to minimise carbon emissions. Examining the effects of aerodynamic forces acting on the vehicle and developing new designs to reduce these forces are very important considering the energy efficiency, the charge and range problems experienced in today's conditions.
In this study, the aerodynamic effect of electric vehicle geometries with different front and rear designs on the velocity distributions around the vehicle was investigated by Computational Fluid Dynamics. Particle Image Velocimetry method was applied inside of a scaled wind tunnel for the validation of these results. The coherence of the experimental and numerical results was evaluated. This evaluation provided validation for the next series of numerical analysis with different flow field parameters. The effects of different geometric design parameters on velocity maps and flow separations were investigated and compared. Numerical analysis of different velocities acting on the electric vehicle
geometries were carried out and the effect of different parameters on the flow region was compared. Also, the effects of different turbulence models on the accuracy were investigated. According to the obtained results, parameters which
minimize the aerodynamic forces on the vehicle were determined.
