In the article, we conducted lattice Boltzmann simulation (LBM) to investigate microscopic two-phase flow behaviors in homogeneous sphere packing medium and heterogeneous porous medium. A two-phase LBM model showed its feasibility to independently investigate effects of contact angle and surface tension on flow behaviors It was observed that liquid water invasion was affected by hydrophobicity of the surface wall in the medium and this was attributed to meniscus formed by liquid and gas phases.
