Flow Simulation and Performance Prediction of a Kaplan Turbine
As it is almost impossible to carry out a prototype hydro-turbine experiment before the power plant is built up, rational prediction of its performance is really expected to design the turbine and to operate the turbine properly. In this paper, as the series of R&D of a numerical test stand for a prototype turbine, we treat hydraulic performances of a prototype Kaplan turbine having a runner diameter of 8 m, which are predicted by using the steady turbulent flow analysis with standard k-ε turbulence model for the entire flow passage. Characteristics curves for on-cam operation are derived from the calculated results, and the performance hill chart is prepared for comparison with the model test results. Reasonable agreement between them encourages us to use the present simulation technique for the performance test of a prototype Kaplan turbine.
