但是，LGA 方法也有许多不足之处。例如，由于含有随机因素，LGA 的计算

结果往往包含很大的统计噪声，LGA的宏观方程也不是标准的流体运动宏观方程。

格子Boltzmann方法正是为了克服LGA方法的一些内在不足而发展起来的一种新

方法。LB 方法的主要特点是以一个单粒子分布函数(实变量)取代 LGA 方法中的

布尔变量。LB 方法不但克服了 LGA 的缺点，-In summary, a systematic investigation is conducted to improve the stability and accuracy

of the LBM for multiphase simulations. A novel LBM model is developed and its

performance is studied in various test problems. The application of the new model in the

simulation of bubble rise, droplet collision, and microchannel bubble formation further

illustrates the enhanced capability of the current LBM model.
