Massive separation control analysis of the pulsed jet actuatorseffects
Published online by Cambridge University Press: 14 February 2014
Abstract
The aerodynamic drag of simplified car geometry with small span and strongly separatedwake can be reduced up 20% by using pulsed jet distributed along the rear window. Resultsshow an enhancement of transversal wake size in the control region, a displacement of themean positions of vortex wake structures, a decrease of velocities near the rear part anda reduction of vortex structure recirculation in the wake. These modifications produced bythe control are analyzed, commented and model based on simple strategy to build efficientand suitable separation control strategy is proposed.
