説明
City-Chino, where the authors are engaged in their work, is located in the slope of Mount Yatsugatake covering altitude ranging from 750 to 2,899m. In this area, water flow from individual source is rather small but experiences a large elevation difference. Accordingly, a small scale impulse type hydroturbine is suitable. In this study, a commercially available micro impulse hydro turbine was tested, whose impeller is interested in because it has an intermediate feature between turgo and pelton impulse turbines. Effects of the water head, number and the diameter of nozzles were tested in a laboratory scale. The generation efficiency for various conditions were measured and correlated with use of the specific rotation speed. In the present study, trial components of an impeller and a nozzle were experimentally manufactured with use of a 3D printer. The obtained impeller attained a comparative performance with the original one. The test nozzle was so produced that its inside diameter was smoothly changed from a thick inlet to a thin outlet. Accordingly, the pressure loss in the nozzle unit was reduced significantly, and thus the new nozzle provided an about 30 % higher efficiency than the original one.
