| 摘 要： | 研究了双向水流侧式进出水口分流墩与进出水口水力性能之间的关系。通过水工模型试验比较，研究分流墩形状及其布置方式对进出水口各孔流道中流量和流速分布以及水头损失系数的影响。针对抽水蓄能电站库水位变化幅度大，在发电和抽水工况下进出水口水流方向相反的特点，拟定了多个试验方案，并对每个方案在高水位及低水位时不同水流方向情况下的水力性能进行试验比较。研究表明，分流墩的形状和位置与双向水流侧式进出水口的水力性能

| Abstract: | This paper presents an experimental study on the effects of guide piers on the flow characteristics at water inlet outlet with two flow directions used in pumped storage plants.The study is focused on the shape and location of the guide piers. Because the water level in the reservoir of pumped storage plants changes within a large range and the water in the inlet outlet flows in two directions, seven models are adopted for several cases.The study indicates that the shape and position of guide piers are of much importance for the hydraulic characteristics of a flank inlet outlet with double flow directions. |
