通过将三维数字显微层析成像技术与格子玻尔兹曼方法相结合，采用一种新的方法来分析多孔介质中多相流的相对渗透率。结果表明，两个耦合系数K12和K21具有相同的大小，因此Onsager互易性仍然成立。该结果与管流数值实验的结果也很好吻合。
By combining three-dimensional digital microtomography techniques with the lattice Boltzmann method, a new methodology is used to analyse the relative permeability of multiphase flow in porous media. The results indicate that the two coupling coefficients K12 and K21 have the same magnitude, therefore the Onsager reciprocity still holds. The results also agree well with the results of pipe flow numerical experiments.
