Capillary pressure in multiphase flow in porous media
 

Any Idea on how to implement the capillary pressure force for multiphase flow through porous media. Capillary pressure will be the difference between the phase pressure in multiphase flow. But in the Euler formulation for two phase flow a single pressure is solved. how do i get the individual phase pressures to implement the capillary pressure model

Any help/pointers will be appreciated.

Thanks
