Abstract

The aerodynamic drag of simplified car geometry with small span and strongly separated wake can be reduced up 20% by using pulsed jet distributed along the rear window. Results show an enhancement of transversal wake size in the control region, a displacement of the mean positions of vortex wake structures, a decrease of velocities near the rear part and a reduction of vortex structure recirculation in the wake. These modifications produced by the control are analyzed, commented and model based on simple strategy to build efficient and suitable separation control strategy is proposed.
