HI, everyone
Has anyone study airfoil pitching motion?
I want to simulation a pitching motion case and compare results with experiment data.

Velocity: around 20m/s
Re: 10e6
Two-dimensional
I chose SST-k omega, Velocity Inlet, Pressure Oulet, SIMPLEC, mesh smooth. However, the lift coefficient changed with time does not match well with experimental data near the maximum angle of attack.

Could anyone give me some advise?
I have wasted lots of time doing this. I am nearly creazy........
