抄録

Development of high specific speed turbine is one of the countermeasure to environment issue. However, the higher specific speed of multi-jet Pelton turbine can leads to the jet interference in the low head, high discharge operation conditions and it causes extraordinary efficiency drop. Authors measured the performance around the jet interference occurring region in prototype and recognized the jet interference starting line is different between model and proto type. On the other hand, FAM, which is the prediction method of the jet interference starting line studied by authors showed a good agreement with the proto type test result. In this study, model test results in which the test head is changed are compared with the FAM results. As the result, a good agreement between analysis results and model test results is obtained.
