The software FLUENT for 3d viscous turbulent flow is used to analyze the influence of gravity on flow field analysis and hydraulic performance evaluation of bulbturbine.
This paper describes the local control unit design of bulbturbine set at Mowu power station in Fujian province, which can be used as reference for the similar type power stations in China.
To increase the head of bulbturbine, it is necessary to improve the runner blade design method and design high head bulbturbine with good energy and cavitation coefficient performance high.
