水电站发电进水口产生旋涡， 这种流态对电站运行极为不利。经结合某大型水电站发电进水口水流流态模型试验， 研究了进水口产生旋涡的原因， 影响因素和破旋措施， 并对现有的经验公式进行修正， 扩大计算范围，力求用经验公式计算代替水流模型试验， 为该类进水口设计提供依据。
Hydropower generating water inlet vortex, this flow is extremely unfavorable to the operation of the power station. Combined with the flow model test of the power generation inlet of a large hydropower station, the causes, influencing factors and breaking measures of the vortex generated at the water inlet are studied. The existing empirical formulas are amended to expand the calculation range and to use the empirical formula Instead of water flow model test, provide the basis for the design of this type of inlet.
