SIMPLE Boundary Conditions

Kunal Jain

If I use the staggered grids and have the half control volumes on the boundary

1.) Would I be putting in some guess values of pressure at that boundary although P correction has to be zero.

2.) Moreover if I specify the guess pressure at the boundary my normal velocity face at that surface and the press. node coincide. Should that be a problem.

Do higher Reynolds number (>500) pose a problem if I have a pure iterative scheme (Gauss -Siedel) of solving the equations.

Any books as to how to treat the boundaries except for Patankar and Peric as I am not too sure how to specify the velocities and pressure at the boundaries. Thanks in advance.
