A quasi-incompressible Cahn-Hilliard-Darcy model for two immiscible fluids in porous media

Daozhi Han, Sayantan Sarkar

We derive a quasi-incompressible Cahn-Hilliard-Darcy phase-field model (qCHD) with the logarithmic Flory-Huggins free energy density function for two-phase flows in porous media. T…
