Multiphase flow modeling in multiscale porous media: An open-source micro-continuum approach [PDF]

open access: yesJournal of Computational Physics: X, 2020
An open-sourced multiphase Darcy-Brinkman approach is proposed to simulate two-phase flow in hybrid systems containing both solid-free regions and porous matrices. This micro-continuum model is rooted in elementary physics and volume averaging principles,
