中文摘要：

基于格子 Boltzmann 方法(LBM ) ，一个改进伪潜力模型，与增加力量术语的一个方法结合了，被用来模仿影响一部液体电影的液体微滴引起的二阶段的流动。在这个模型，不同阶段被当作在蒸汽之间的一液体，和接口，液体阶段能被液体的密度价值获得。LBM 的这变体允许一个与高精确性获得蒸汽和液体的密度。模型被阶段分离的一个例子验证。液体电影上的微滴的影响的早阶段被模仿，并且结果是与物理现象一致的品质上。

英文摘要：

Based on the lattice Boltzmann method（LBM）,an improved pseudo-potential model,combined with a method of adding force term,is used to simulate the two-phase flows caused by a liquid droplet impacting on a liquid film.In this model,the different phases are treated as one fluid,and the interfaces between the vapor and liquid phases can be obtained by density value of the fluid.This variant of the LBM allows one to obtain the densities of vapor and liquid with high accuracy.The model is validated by an example of phase separation.The early stage of the impact of droplet on liquid film is simulated,and the results are qualitatively consistent with physical phenomena.
