Fig. 7From: Experimental study on airfoil flow separation control via an air-supplement plasma synthetic jet2D airfoil upper surface velocity contour under different actuation states. Black arrows: velocity profiles at selected streamwise locations; solid black line: dividing streamline; dotted black line: contour lines of Uc = 0 (referred to as zero-velocity lines); the jet orifice position is indicated by a red arrowBack to article page
