Boundary Conditions for 2 d N S equationsHi,
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. Vivek |
