Small hydropower development is one of the best way for enhancement of energy security and good solution of global environmental issues. A new submerged impulse turbine has been developing for generation by replacing a pressure reducing valve in drinking water pipe lines. This study has been especially focused on torque loss on the turbine, but it is not fully understood the reason why the loss is occurred. The torque loss is serious problem for a submerged turbine performance. Thus the torque loss on the runner and a disk was measured. This study, therefore, focuses on the loss mechanisms and aims to reveal key parameters for the loss reduction. We measured and compared to the torque loss between a simple disk and the submerged impulse runner experimentally. In addition, we aimed to reduce the agitation loss with the runner blade.
