| Research Abstract |
It aimed at developing eco small water turbine that it was possible generate power with high efficiency from hydraulic energy of extremely low head, less than 2 m. It was especially focused on shape of blade and channel, sophisticated blade surface and investigated for improvement of turbine performance. Two kinds of turbines, waterfall type turbine and Savonius turbine, were tested. As a consequence for waterfall type turbine the cross flow shaped runner shows better performance under wider range of rotation speed than that of the impulse runner. The curved shaped channel was shown to be effective in control of waterfall position, and then it was possible for stable generation. Theperformance test adopted hydrophilic or hydrophobic blades on Savonius runner was not observed significant difference.
