摘　　要：利用粒子之间相互作用 ,即同种物质粒子相互吸引 ,异种物质粒子相互排斥这一物理化的原理研究并提出了一个新型的模拟多孔介质中二相驱离的格子玻耳兹曼模型 ,结果表明它能有效地模拟多孔介质中的二相驱离问题 ,且节省机时 ,分界面上涨落也小 。By using the interaction of particles,such as the physical principle of the same attract each other and the different repulse each other,a new model of Lattice Boltzmann to simulate the two-phase driven in porous media was discussed. The result shows effectively for the problem of two-phase driven in porous media. Furthermore,the method economizes on computer time, has less fluctuation on boundary surface and takes no average measure.
