Strategy of the flow mems control at laminar-turbulent transition in a boundary layer

摘要

Present work is a continuation of the investigations [2],where a passive method of the stationary vortex control by riblets in the transition region of a three-dimensional flow was tested suing the method of the control distrubances.Below we propose in the same way two methods of the active control in such flow:the wave cancellation and a localised point-like suction.
