Boundary Conditions for 2 d N S equations
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.
