Design and analysis of Pelton turbine buckets

Abstract

The Pelton turbine can be used as a two-phase expander. The
characterization of the Pelton turbine as two-phase expander
consists in analyzing the power loss sources to evaluate the
machine performance. The design of Pelton turbines has always
been more difficult than that of reaction turbines, and their
performances lower.
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
bucket are very often the limiting componenet of pelton
turbines. To survive n this difficult environment, blades
often use exotic material.
In this project,pelton turbine is designed and modeled in
3d modeling 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
structural steel,low carbon steel and maraging
steel.Optimization s done by different material by
performing coupled field analysis on the designs.
