摘要
利用k-ε紊流数学模型对某抽水蓄能电站上水库盖板竖井式进 /出水口进行了数值模拟.针对有无拦污栅的情况,分析了拦污栅对进 /出水口流速分布和水头损失等的影响.就整个进 /出水口而言,不模拟拦污栅,其结果基本能反映进 /出水口的水力学特性.
The numerical simulation on the hydraulic characteristics of a shaft intake with cover for the upper reservoir of a pumped storage plant is made with k-ε turbulent model, in which the effect from trash rack on the loss of water head and the flow distribution at the intake/outlet with or without trash rack are analyzed. For the whole intake/outlet, the result shows that the simulation made by physical or mathematical model can reflect the hydraulic characteristics of the intake/outlet basically under the condition without the trash rack is simulated.
