摘要
在工程实践中发现,泄水陡坡后消力池优化设计中,往往需要物理模型试验验证,比较费时费力。该文采用标准k-ε模型、及RNG k-ε模型,对不同消力池内部水流进行数值模拟,得出消力池内水流运动参数;通过与物理模型试验结果对比,发现RNG k-ε计算模型对消力池内部复杂水流模拟效果较好。今后实践工程优化中,可运用RNG k-ε计算模型进行消力池内部水流模拟计算,优化消力池的设计参改。
Found in engineering practice , optimization design of Stilling basin behind sluice slope , physical model test often requires to be done , which is time-consuming .Numerical simulation is carried out on the different internal flow stilling basin by using standard k-ε model and RNG k-ε model, and then got the stilling basin water movement parameters; By comparing with model test results , it is found that the RNG k-εcalculation model for stilling basin complex internal flow simulation effect is better . In the engineering optimization in the future , using the RNG k -ε internal flow stilling basin is simulated calculation model to optimize the design parameters of stilling basin .
