摘　　要：为提高抽水蓄能电站进/出水口过栅流速均匀性,采用标准κ-ε紊流模型,对不同方案下的蛟河抽水蓄能电站进/出水口过栅水流流态进行了数值模拟。结果表明,在进/出水口其他尺寸符合常规的条件下,减少分流墩厚度(最小厚度取决于结构安全需求)可明显提高过栅流速均匀性。For improving the uniformity of the flow across the trash rack in inlet/outlet of Jiaohe Pumped Storage Power Station,the standardκ-εturbulence model is adopted to simulate water flow under different plans.The results show that while other dimensions of the inlet/outlet are in line with the conventional conditions,reducing the thickness of the splitter pier can significantly improve the uniformity of the flow across the trash rack.
