Abstract

Simplified vehicle has been applied in this paper to study the influence of wheel spoiler height on vehicle drag reduction. Two different conditions including stationary and rotating wheels were employed in numerical simulation with steady RANS (Reynolds Averaged Navier-Stokes) equations. Based on detailed analysis of flow around the wheels and integral curve of vehicle drag, it can be concluded that for both the stationary and rotating conditions, the drag decreased first and then increased as the spoiler height gets bigger. For front wheel spoiler, the optimal wheel spoiler height for stationary conditions lower than rotating one due to different drag reduction mechanism, so in wind tunnel test rotating condition was performed.
