Hello Nate, 

the area-weigthed average tangential velocity will really only work for a circular motion of a cylindrical domain. If you know the radius and tangential velocity of this motion, you can work out the angular velocity. You really only need 1 point that has these two quantities over time. The area-averaging is only to reduce the noise in this calculation.

 You can read about how Tangential velocity is defined here: 41.2. Velocity Reporting Options (ansys.com)

In your case, with airfoils, I still recommend using the data from Motion History.
