Darcy Scale Modeling For Two-phase Flow In Porous Media From A Dynamic Pore-scale Network

A modified dynamic pore-scale network model, is presented with an emphasis onthe dynamic effect of the micro fluid in the pore scale, such as slip boundary conditionfor the moving contact line (general Navier condition) and dynamic capillary pressure.Based on the pore scale model, we simulate the drainage process for the two phaseimmiscible flow. The capillary pressure-saturation relationship and relative perme-ability-saturation relationship are obtained, which are essential to the closeness of theDarcy scale modeling.
