离散液滴模型中几个重要问题的探讨

Discussion of Several Important Problems in Discrete Particle Model

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。

Some important problems in discrete partical model which is used to calculate the two-phase spray flow in constant volume chamber, such as droplet grouping, tracking, interaction between two phase vaporization, and the influences of droplet vaporization, collision and turbulent motion submodels the spray flow simulation are discussed.
