Abstract

The hydraulic performances of a Francis turbine which had been designed and tested by IMHEF were calculated with a commercial code and compared with the IMHEF test results. The non-dimensional specific speed of the turbine is 0.5, the runner exit diameter 0.4m and maximum efficiency 93.1% respectively. To make the calculation of the turbine more exact, the stay vanes, the guide vane, the runner and the draft tube were calculated simultaneously. The calculation results gave a quite good agreement with the IMHEF test data, and therefore it is expected that the present calculation technique will be utilized for the hydraulic design of efficient Francis turbines.
