To increase the head of bulb turbine, it is necessary to improve the runner blade design method and design highhead bulb turbine with good energy and cavitation coefficient performance high.
Low applicable head, high flow and high efficiency characterize bulb type tubular turbine unit. These kinds of units are widely used for the development of low-head water resources.
