This work assesses conservative level set method (LSM) and Cahn–Hilliard phase field method (PFM) in modeling 2D two-phase flow through porous media, based on their ability to capture different phenomena associated with the medium permeability and fluid viscosity contrasts. The assessment includes their accuracy and running time. For this purpose, a robust finite element solver (COMSOL Multiphysics™)...
