摘要
结合二滩水电站、小湾水电站、洪家渡水电站和天生桥一级水电站,采用k-ε紊流模型对其进水口水力特性进行了三维数值模拟,对进水口水头损失、流速分布及流态等方面进行了总结。数值模拟结果得到了模型试验结果的验证。
Combined with Ertan Hydropower Station, Xiaowan Hydropower Station, Hongjiadu Hydmpower Station and Tianshengqiao Hydropower Station I, a 3D numerical simulation is made on the hydraulic characteristics of intake for hydropower station with κ-ε turbulent model; from which the head loss, velocity distribution, flow pattern, etc. are summarized. The numerical results are validated by the physical model experiment concerned.
