| 低浓度和高浓度固液两相流运动可以通过微观动理论加以描述[1].本文在文献[1]的基础上，探讨固液两相流在低浓度和高浓度情形下的应用方法，以颗粒浓度垂线分布为例进行分析，获得了满意的结果，也揭示了高浓度固液两相流的一些特点. |
| 英文摘要: |
| This paper presents the application of kinetic theory to low concentration and hyper-concentrated flow. It is indicated that the kinetic theory for a solid-liquid two-phase flow gives reasonable microscopic descriptions of the motion of sediment particles and their interaction. The mechanisms of low concentration and hyper-concentrated flows are quite different due to the different dominant actions. The former is controlled by the liquid action or liquid-solid interaction, while the latter is principally controlled by the interaction between particles. These essential differences can be well described by the kinetic theory rather than by the traditional theories. The kinetic theory is compared with the experimental results both for low concentration and hyper-concentrated flows. Satisfactory agreement is attained. |
