Three-dimensional structures behind Glauert-Goldschmied profile under control of plasma actuation

The effect of plasma dielectric barrier discharge (DBD) to developed boundary layer was investigated previously. It has been shown that plasma actuation can stabilize the flow near to the surface. In the case of streamlined profile, the plasma actuation is able to shift the point of separation and hence to suppress the extent of separation area. This should lead to decrease of the form drag and increasing the total efficiency. An experimental approach is suggested for investigation and time-resolved Particle Image Velocimetry (PIV) is considered as a main measurement technique.
