摘　　要：为优化多级陡坡消力池设计尺寸,本文采用k-ε双方程模型结合VOF模型的数值模拟方法,对多级陡坡消力池内部水流进行三维水气两相流数值模拟。通过模拟校核工况下多级陡坡消力池流场,得到了模型内部水气两相流云图及流速矢量云图,经分析得出多级陡坡消力池第一二级池深、第三级池长有待优化的结论。本研究成果为优化多级陡坡消力池尺寸提供了理论依据。In order to optimize the design size of the multistage steep slope basin,this paper adopts the numerical simulation method oftwo-equation model combined with the VOF model,the three-dimensional numerical simulation of the two-phase water and gas flow in the multistage steep slope basin is carried out.By simulating and checking the flow field of multistage steep slope basin,the cloud diagram of two-phase flow and velocity vector cloud diagram of the model are obtained.The conclusion is that the depth of the first and second level and the length of the third level should be optimized.The results of this study provide a theoretical basis for optimizing the size of the multistage steep slope stilling pool.
