Lift hysteresis of oscillating NACA0012 airfoil

Hi all,
I am running a case of oscillating airfoil and I get lift coefficients such that as the angle of attack (aoa) increases the lift coefficient decreases and vice versa. Basically, the hysteresis loop is rotated 90 degrees. When I try to get static lift coefficients I get correct behaviour but for dynamic pitching what I mentioned is happening. Any one has an idea? |

Hi
Have you figured out the problem why lift hysteresis curve is rotated 90 degree. If so kindly help. |
