Separation is delayed by means of a jet vortex generator in a form of small jets injected to the boundary layer through orifices distributed across the main flow. The effect of jets intensity on delay of separation is examined. Swirled and non-swirled jets have been used. The energy of the air supplying the generator required to delay boundary layer separation is in the former case up to 40% lower than in the latter one.}, type={Article}, title={Discrete air jets employed to control boundary layer separation}, URL={http://journals.pan.pl/Content/124973/PDF-MASTER/8_MECHANICAL_52_2005_2_Szumowski_Discrete.pdf}, keywords={discrete jet, active control, boundary layer}, }
