Abstract
An improved J-shaped blade, in which a J-shaped blade is combined with a small-size Savonius blade, has been developed, to further improve efficiency of an air turbine for wave power generator systems. A prototype model of stationary wave power generator has been developed using the improved blade, to confirm its power generation characteristics by tests in a water tank and small-scale ocean tests. The results are compared with the characteristics of the units with conventional blades. The air turbine unit with the improved blade shows an efficiency of 13 to 35%, which is higher by 10 to 20% than that of the turbine with a J-shaped blade and by 20 to 70% than that of the one with a Savonius blade, more noted at low speed of rotation. It is therefore considered that the turbine with the improved blade is suited for sea areas having a relatively low wave height. It is also considered that efficiency can be further enhanced, when one or more guide vanes are provided around the blade. 2 refs., 12 figs.
