Flow statistics of spatially developing turbulent boundary layers with localized application of three different control techniques aimed at reduction of skin friction drag.

Simulations of spatially developing turbulent boundary layers with localized application of three different control techniques aimed at reduction of skin friction drag. Considered control techniques are uniform blowing, body-force damping of wall-normal velocity component and opposition control. Stroh, A., Hasegawa, Y., Schlatter, P., & Frohnapfel, B.
