旋流竖井段水力特性数值模拟

Numerical Simulation for the Hydraulic Characteristics of Swirling Flow of Inner Dissipation with Shaft Inlet

采用标准κ-ε模型和VOF方法相结合,实现了水平旋流竖井段的水力特性的数值模拟.并计算了不同收缩比起旋器出口情况下竖井段的水力特性。模拟计算结果与试验结果对比表明,旋流竖井段的水力特性采用这种标准κ-ε模型的模拟效果较好。

Following selecting the κ-ε turbulent flow model and the VOF way to carry on the computation, we have got the hydraulic characteristic of the level swirling flow with shaft inlet by numerical simulation and contrasted with the test result. From the results, we know that the κ-ε turbulent is good at getting the hydraulic characteristic of the level swirling flow with shaft inlet.
