Abstract
Darrieus-type hydro-turbine system has been developed for low head hydroelectric power generation. When Darrieus-type hydro-turbine with/without two-dimensional symmetric inlet nozzle is operated in open channel flows like river and agricultural water way, generated power is known to be increased by installing inlet nozzle. In this research, the effects of converging angle and nozzle outlet width on turbine performances are investigated in order to find the ideal shape of inlet nozzle. As a result, the turbine with the inlet nozzles having converging angle of 45 and 60 degrees can generate larger power than that with 30 degrees under the constant nozzle outlet width. The turbine with the inlet nozzle whose outlet width is 0.9 times diameter of runner pitch circle produces larger power than those with the narrower nozzle outlet widths.
