we have at each cell descretised equation in this form,

 a_p \vec v_P  = \sum\limits_{neighbours} {a_l } \vec v_l  - \frac{{\nabla p}}{V}  ;
 \left[ {\frac{1}{{a_p }}H} \right]_{face}  = \left[ {\frac{1}{{a_p }}\frac{{\nabla p}}{V}} \right]_{face}

where

 H = \sum\limits_{neighbours} {a_l } \vec v_l

This interpolation of variables H and  {\nabla p} based on coefficients  a_p for pressure velocity coupling is called Rhie-Chow interpolation.
