摘要
液固两相流是液相介质与固相介质的混合物,是固相颗粒悬浮在液相介质中的混合物或混合介质。河流冰塞常导致洪水灾害,河冰运动应属于固液两相流的范畴,依据多相流理论对河冰运动颗粒的驰豫过程和极限浮速等进行了尝试分析,所得结果不仅可作为进一步研究冰塞理论和相关数值模拟的基础,也可供物理模型研究和工程实际参考。
The movement of the mixture of liquid and solid belongs to two-phase flow,and it is often seen that solid particle cloud float and move in fluid. Flood could be brought from the appearance of ice jams, and ice motion in a river is a kind of phenomena of two-phase flow.In the paper,an analysis of the relaxation process of ice particles and ice floating up is made based on the theory of two-phase flow. The obtained results provide a basis for the numerical simulation analysis.
