| Research Abstract |
It has been a major challenge that twigs and leaves flowing into the water turbine block the impeller passage, causing non operating condition or output reduction state in the micro hydropower utilization. By using the single-blade sewage pump as reverse water turbine, it was clarified by numerical analysis and experiment theinternal flow and relationship of water turbine characteristics and pump characteristicsin this study. Moreover, it was found to be able to achieve high-efficiency and the reduction of the radial thrust by using the two-blade reverse water turbine.
