格子Boltzmann方程模拟不相溶二相流体运动理论

Simulation Theory of Immiscible Two-phase Fluid Flows Using a Iattice Boltzmann Equation

在碰撞项中引入了异类粒子的排斥势，用它取代着色粒子密度重新分布过程，完全克服了人为因素．理论推导表面张力系数的表达式，用以比较模拟的结果，为格子Ｂｏｌｔｚｍａｎｎ方法模拟不相溶二相流体运动提供了理论依据．

A repulsive potential of different particles is introduced into collision term toreplace the redistribution process of colored particles so as to get over man-made factor.The expression of surface-tension-coefficient deduced provides a basis for the simulationtheory of immiscible two-phase fluid flows using a lattice Boltzmann equation.
