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

<div>Comparison of the normalized circulation in the planar control region during one pitching cycle for the two different airfoils. The pink region represents that the TEF deflects upwards. The gray region represents that the TEF deflects downwards.</div>
