Single Component, Multiphase Fluids Flow Simulation in Porous Media with Lattice Boltzmann Method

In this paper, a single component, two-phase flow simulator is developed to investigate the behavior of isothermal two-phase fluid flow in porous media. The simulator is based on the lattice-Boltzmann method and the Shan-Chen multiphase model of nonideal fluids that allow coexistence of two phases of a single substance. We reproduce some different idealized situations in which the results are already known from theory or laboratory measurements and show the validity of the implementation for the physical two-phase flow in porous media. Application of the method to fluid intrusion in porous media is discussed and shows the effect of wettability on the fluid flow. The capability of reproducing critical flooding phenomena under strong wettability conditions is also proved.
