紊流模型对双向进出水口数值模拟的影响
首发时间:2008-09-25
摘要:运用四种不同的紊流计算模型对抽水蓄能电站上库侧式进出水口的水力特性进行数值计算,得到不同紊流模型下的进出水口流速分布、水头损失等水力特性,并将计算结果与模型试验结果进行比较,得到不同的紊流模型对进出水口流速分布、水头损失等水力特性的影响,计算结果表明四种紊流模型均适合于进出水口数值计算。

The Effect of Turbulence Model on Numerical Study of Intake with Two-Direction Flow
Abstract:The hydraulic characteristics of pumped storage power plant lateral intake such as velocity distribution and the head loss has been studied by four different turbulence models, Obtained the hydraulic characteristics such as velocity distribution and the head loss, the results has been compared with the model test results, get the impact of turbulence model to the hydraulic characteristics, the results showed that four turbulence model suitable for access points are calculated.
Keywords: turbulence model numerical study hydraulic characteristic
