采用离散液滴模型对定容室中的喷雾两相流进行了计算，讨论了液滴轨道模型中液滴分组、追踪及相间作用等问题，并考察了蒸发模型、碰撞模型、液滴湍动模型对计算结果的影响。
The discrete droplets model was used to calculate the two-phase spray flow in the fixed volume chamber. The problems of grouping, tracing and interphase of droplets in the droplet orbit model were discussed. The effects of evaporation model, collision model, Impact of the model on the calculation results.
