Default flow over a 2D cyl using SIMPLE
Posts: n/a
Hi everyone

Although the original SIMPLE formulation was through finite volume, I believe that the SIMPLE algo can also be used for a finite diff. formulation provided the equations used are in the conservation form, which are derived by considering a fixed infinitesimal fluid volume in space.

I would like to know what the important considerations are while using a finite diff. formulation for SIMPLE and also if a non conservation form of equations can be used. Say for e.g. if I were attempting to solve the incompressible flow over a 2D cylinder using a polar grid using SIMPLE, would I have to consider the conservation form of the transformed N-S equations?

Any advice would be greatly appreciated. Many tanks in advance.

1.For this particular problem you need not use the transformed equations.You can solve it premitive variables it self. You say u r using finite difference scheme Simple will work . Just Discretise the N.S ( premitive variables will do)and try it out.
