Trailing Edge Flap Effects on Dynamic Stall Vortex and Unsteady Aerodynamic Forces on a Pitching Airfoil

Figure 23

Streamlines and Mach number contours around the leading edge at for the two airfoils: (a) original airfoil and (b) TEF airfoil. The solid white line represents the contour line that the normalized vorticity is -10.
