Performance Analysis for an Impulse Turbine – A Case Study

Abstract

Performance test on a model of a Pelton turbine has been carried out in the laboratory for various gate opening of the turbine. The parameters have been expressed in the term of unit quantities. The result show that the peak efficiency lies between 70% and 90% of the full load. The maximum efficiency and power obtained at Nu =135, whereas maximum efficiency obtained is 66% at 90% wicket gate opening, Predicted result based on the modal study for a prototype obtained is within the specified limit.
