Unsteady flow- pressure velocity coupling
 

Hi,
I am trying to use the SIMPLE Algorithm so that I can then use the Rhie-Chow interpolation method to solve a Navier Stokes Equation. I will be using the Crank-Nicolson method for time discretization. I was wondering if the Crank-Nicolson can be used when the Simple algorithm is being use or do I have to use a fully implicit approach for time discretization instead?

If so, in this case I have to sue the Crank-Nicolson approach, so what other approach can I use instead of the SIMPLE algorithm.

I would appreciate any hints as soon as possible.

Thanks!
