Dear all,

When solving multiphasic Navier-Stokes equations, many authors introduce the dynamic pressure pd= p-pc. To quote one of them:

"To avoid the difficulties in discretization of the capillary pressure jump, we write the momentum balance equation in terms of a capillary pressure

pc and a dynamic pressure pd = p- pc"

Could someone direct me to a paper or book that explain the necessity of it in more details?

Thanks
