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

TechnicalRemarks: 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.
