Abstract
The interaction of turbulent flows with the external structure of ground vehicles generates uncomfortable noise and a lot of attention is devoted to find new mechanisms for its suppression. The present work is concerned with open cavity flows, very often found in the automotive industry. A three-dimensional rectangular very wide open cavity with aspect ratio L/D=4 at Reynolds number ReD=5000 and Mach number M=0.1 is considered. The passive control technique is based on eight different geometrica...
