Numerical investigation of boundary layer detachment by active flow control

International audience; After decades of investigations have failed to produce a positive outcome on flow control technologies that requires complex devices and micro-plumbing, recent technologies like synthetic jets, DBD (Dielectric Barrier Discharge) seems to be promising and these technologies can overcome limitations of the old ones. Our work mainly deals with delaying boundary layer detachment of over an aerodynamic body (Air foil). In this paper we produce our study of an active flow control device over the BL detachment point over a circular cylinder by the aid of simulations. Results from the uncontrolled flow seem to be in accordance with literature and the presence of the jet has …
