In this article, we employ a recently introduced numerical technique, known as lattice Boltzmann method (LBM), to numerically simulate immiscible two-phase flow in microscopic models of porous media. This model takes into account the ratio of (dynamic) viscosity, density, interfacial tension, and wettability, . The two-phase flows of supercritical CO_2 and water in a straight channel with a lot of hexagonal cylinders (imitation porous media) were simulated numerically to show the effect of (dynamic) viscosity ratio on the permeability of porous media. The imbibition of wettable liquid into porous media driven by capillary pressure can be simulated successfully.
