灯泡混流式水轮机流道系列的设计

Research and Design of Flow Series for the Bulb Francis Turbines

从水力性能和水流运动规律出发，对灯泡混流式新型水轮机的流道进行了研究，提出了确定灯泡混流式水轮机过流通道的系列几何形状及参数的方法，得出灯泡混流式水轮机的最佳应用水头范围为20～300m。本设计可为新型水轮机的产品开发和设计提供重要的参考依据。

A research on the flow passage of the Bulb-Francis turbine is conducted based on hydraulic performance and water flow rule,which leads to the raise of the geometry and size series of the flow passage of the Bulb-Francis turbine.The study performed offers important material for the product development and design of this type of turbine.Meanwhile,the best applicable range of water head for it is considered to be ranging from 20 to 300 meters.
