In recent years, Environmental problems are becoming serious. For example, large amounts of CO_2 by thermal power generation cause global warming, and there is a strong demand for the spread of the power generating system by clean energy. Therefore we pay attention to micro hydro-power generation. Reverse running pump turbine would be used as a small hydro-turbine because of reliability and sales performance of pump. However, performance of the reverse running pump deteriorates by foreign substances and it occasionally falls into non-operating condition. These problems are important in working running pump turbine, and it is necessary to improve them. On the other hand, single-blade centrifugal pump has an outstanding characteristic to keep wide flow passage. Then, a single-blade reverse running pump turbine was adopted for a small hydro-turbine with excellent non-clogging characteristics. The relationships between turbine and pump characteristics of single-blade reverse running pump were investigated by and experiment and CFD in this research.
