Abstract
In the modern society, environmental problems become serious for influence of global warming. We have developed micro generation system for effective use of unutilized energy and the spread of a self-controlled dispersion energy supply system. The turbine blade was designed by special shape. The turbine was named tornado type turbine. We could realize a turbine with a very complicated shape with a 3D printer. Using 3D printers, it was possible to quickly generate various shape models, and we could compare the hydraulic performances of the seven different turbines. The theoretical output was also calculated using the inflow velocity obtained from the experimental data of each shape model. We found a blade shape for efficiently converting fluid energy into rotational energy.
