Abstract
Recently various measures are made towards realization of low carbon society. Water-power generation is one leading policy. However, development of the small-scale water-power generation to power consumption, such as a plain part, is not fully progressing. Therefore, this research aims to develop the micro water-power generation equipment which used the new type of turbine. For developing new type of turbine called the tornado type, its prototype model experiment and numerical simulation are performed and the various parameters of the turbine are determined and the manufacturing checks are performed. Then, we conducted the profile data of turbine generated by the 3D-CAD, production of the prototype model by using RP equipment, and the check experiments of operation by the produced the prototype model. Moreover, cutting of the actual turbine by using 5-axis processing machine with the tool path data generated by the 3D-CAM was also performed. As a result, we confirmed that the rapid prototyping model is possible to rotate in the water flow. In addition, in the actual cutting experiment of the turbine, we confirmed that it is possible to manufacture of the turbine by 5-axis processing machine.
