| 摘 要： | 利用RNG 紊流模型，采用有限体积法和结构化网格，对虹吸式出水管进行数值模拟。由数值模拟结果分析了虹吸式出水管内部水力特性，并通过改变影响虹吸管水力特性的几个主要参数对原方案虹吸管进行了水力优化。优化方案较原方案进行比较，在水流流态、压力分布和水力损失方面，均有明显改善，可为虹吸式出水管设计提供参考。

Numerical simulation and hydraulic optimization for siphon outlet pipe of pump station |
| |
| Abstract: | With the finite volume method and unstructured grid, RNG turbulent model is adopted to simulate the interior three-dimensional flow of siphon outlet pipe. On the basis of numerical simulation results, analysis of the pipeline internal hydraulic characteristics, and put forward the Siphon outlet pipe optimization scheme by changing the main parameters influencing the siphon hydraulic characteristics. Comparing the optimization scheme with the original scheme, optimization schemes were obviously improved in the flow regime, pressure distribution and hydraulic losses, it can provide a reference for the siphon outlet pipe hydraulic optimization design. Key words: siphon pipe; numerical simulation; hydraulic optimization |
