Flow control and shape optimization

• Flow control : (2011) Participants CHB, Iraj Mortazavi, Emmanuel CreusŽ (Lille), Patrick GilliŽron (Renault chercheur indŽpendant !) An efficient active control of the two- and three-dimensions flow around the 25¡ rear window Ahmed body has been performed. A careful theoretical and numerical study of the trajectories of the vortices allows to adapt the control in order to improve its efficiency and get a better drag reduction.
