Flow control and shape optimization
Flow control : (2011) Participants CHB, Iraj Mortazavi, Emmanuel Creus (Lille), Patrick Gilliron (Renault chercheur indpendant !) 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.
