Design and Static Analysis of Pelt on Turbine Bucket

Abstract

A pelton turbine bucket is the individual component which makes up the turbine section of a pelton turbine. The blades are responsible for extracting energy from the high pressure water produced by the nozzle jet. The pelton buckets are often the limiting component of pelton turbines. To survive in this difficult environment, blades often use exotic materials In this project, pelton turbine bucket is designed and modelled in 3D modelling software CATIA V5. We know that the efficiency is directly related to material performance making the material selection of primary importance. In this project, materials considered for turbine blade are steel, cast iron and fiber glass reinforced plastic. Optimization is done by varying these materials by performing coupled field analysis on the turbine blade for both the designs. The objective of this project is to perform coupled field analysis of pelton wheel bucket for various materials and varying the number of buckets on the pelton wheel for finding out the efficiency, high stress handling factors.
