This research based on Eulerian—Larangian turbulent models,numerical simulate the sand particle water in the whole passage.

基于Eulerian—Larangian湍流模型对一含沙水流中水轮机全流道流场进行了数值模拟,得出不同断面上的速度分布图,含沙水沙粒的运动轨迹和对机组效率的影响。

Therefore, the simulation in whole passage is necessary.

由于水轮机模型试验预测原型机压力脉动不可靠,而水轮机单流道或单个过流部件的CFD模拟计算由于没有考虑各过流部件之间的耦合干涉,其预测结果也存在较大偏差,所以,非常有必要进行全流道的各过流部件耦合计算来预测水轮机的整体特性。
