FEM Analysis of Turgo Impulse Turbine Blade

Sourabh KHURANA, Varun GOEL, Anoop KUMAR

Abstract


The present research work describes the development of Turgo turbine blades on the Solidworks software. Finite element simulation (Ansys V14) has been used for analysis of stress and total deformation produced inside the Turgo impulse turbine. Finite element simulation is effective when it is used to analyze the strain and stress distribution. It has been observed during analysis that the maximum stress occurs at the root of blade suction side.


Keywords
