摘要
利用k-ε双方程紊流模型,采取瞬态PISO算法求解压力—速度耦合的方法,结合VOF追踪自由表面对溢洪道体形进行数值模拟优化,得到了溢洪道内流态、沿程水深和底板压力的分布。通过物理模型试验验证,两者结果吻合较好,说明数值模拟方法能方便地应用于溢洪道体形优化。
The spillway shape of Liangchahe Hydropower Station was optimized with k-ε two-equation turbulent model,transient PISO algorithm for solving pressure-velocity coupling,and VOF method for tracking the free surface,and the flow pattern,water depth along the way and bottom pressure distribution were obtained.The numerical simulation is consistent with physical model test.
