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

<div>Comparison of aerodynamic force coefficients between the original and TEF airfoils in the time domain: (a) lift and drag coefficients and (b) pitching moment coefficients. The pink region represents that the TEF deflects upwards. The gray region represents that the TEF deflects downwards.</div>
