摘要
利用k-ε紊流数学模型,对某抽水蓄能电站75°非对称引水岔管水力特性进行了三维数值计算,分析了不同工况下该体型岔管的压强分布、流速分布、压强与流速沿轴线变化以及水头损失,其中水头损失计算值与试验值进行了比较。最后,对岔管体型和运行方式提出了建议。
The water flow in 75° asymmetry diversion bifurcated pipes in Xilongchi Pumped-Storage Plant was calculated by 3-D - turbulence model. The hydraulic characteristics, including pressure distribution, velocity distribution, the changes of pressure and velocity along pipe axis, and water head loss, were analyzed under various conditions; the water head loss calculated was compared with the experimental data. And the type of bifurcated pipe and the operating mode were suggested.
