基于非恒定流过渡过程计算的水电站调压室优化设计

Hydropower Station Surge Chamber Design Optimization? Based on Unsteady Flow Transition Process Calculation

长引水系统水力计算的主要内容和根本实质就是计算调压室的大、小波动及水力干扰过渡过程,以确定调压室的断面结构,这是重点,也是难点。介绍了基于非恒定流过渡过程的计算方法,并据此计算方法结合渡口坝电站工程实例优化了调压室的设计方案。

The essence and main content of hydraulic calculation of long water diversion system is the calculation of fluctuations in the surge chamber and hydraulic interference transient,especially the calculation of structural cross-section of surge chamber.The calculation method based on unsteady flow transition processes was introduced firstly,and then the design of surge chamber of Dukou Hydropower Station was optimized based on this calculation method.
