Research and Design of Bulb-Francis Turbines

The runner of a francis turbine is applied to a bulb turbine in this work.Therefore,the basic principle,hydraulic performance,flow motion law and hydraulic design theory of flow parts of this bulb-Francis turbine are introduced,and the structure design method is put forward.And through analysis and research,it is found that this new type of turbine has advantages of both francis and straflo turbine,avoiding their disadvantages.Consequently,it can replace the most widely-used modern francis turbines within wider applicable head range and can be widely used in small and medium-sized hydraulic power stations.
