Rhie-Chow interpolation
From CFD-Wiki
we have at each cell descretised equation in this form,
- ;
For continuity we have
where
This interpolation of variables H and based on coefficients for pressure velocity coupling is called Rhie-Chow interpolation.
the Rhie-Chow interpolation is the same as adding a pressure term, which is proportional to a third derivative of the pressue
