Hi,


I am trying to solve vorticity form of 2D Navier stokes equation for flow around circular cylinder. I have to rotate my cylinder .

My boundary condition for a stationary cylinder in terms of psi would be

psi on the cylinder would be 0 since velocities are zero

Now my cylinder is rotating with a constant velocity
My psi still will be zero because of constant velocity

How would I incorporate such B.C I can only give B.C .

Any Help would be much appreciated.
