DESIGNING OF HYDRO TURBINE USING CFD

Abstract

The aim of the present work is to carry out the free surface flow in a Pelton turbine bucket. Steady state numerical simulation has been done for the single bucket, for this the fixed configuration of Pelton turbine bucket is considered. The dimensions of the bucket are to be varied for the same conditions of discharge, head, and inclination of bucket to the jet. The numerical analysis is performed with the FLUENT code. The results provided by the analysis are compared for two profiles of Pelton buckets. The flow patterns in the buckets are analyzed from the results. An analysis of the losses due to the edge and the cutout of the bucket is also done. These results give the details as per expectation of steady flow calculations through the optimization process of the design of pelton turbines.
