侧式短进出水口水力试验及体型优化

Experimental research and shape optimization on lateral short inlet/outlet

本文结合大树子抽水蓄能水电站下库进出水口试验任务,对侧式短进出水口在不同工况下的流速分布、水头损失、库区流态等水流特性进行了水力模型试验研究。对原设计体型成功进行了优化,使各项水力参数达到比较理想的效果,解决了抽水蓄能电站侧式短进出水口在出流时流态分布不均匀与水头损失系数偏大的难题。

A series of hydraulic model experiments of water flow, head losses and flow state in reservoir under various conditions are carried out for the design of the Dashuzi pumped-storage plant. In the experiments, the primary shape is successfully optimized so as to make the hydraulic parameters better, the problems of lateral short inlet/outlet of pumped-storage plant in which water flow is asymmetric and head loss is too great are all resolved.
