Abstract: The Pelton wheel is an impulse type water turbine. It was invented by Lester Allan Pelton in the 1870s. The Pelton wheel extracts energy from the impulse of moving water, as opposed to water’s dead weight like the traditional overshot water wheel. Many variations of impulse turbines existed prior to Pelton’s design, but they were less efficient than Pelton’s design. Water leaving those wheels typically still had high speed, carrying away much of the dynamic energy brought to the wheels. Pelton’s paddle geometry was designed so that when the rim ran at half the speed of the water jet, the water left the wheel with very little speed; thus his design extracted almost all of the water’s impulse energy—which allowed for a very efficient turbine. In general all solid and non solid model will deform when certain amount of thermal or structural loads applied within the environmental condition. In order to find the changes of the product or component, a analysis software is used. Ansys is an analytic software to find changes in deformation, Product life, Failures, heat flux (change of heat flow with respect to time and distance) and CFD (flow of air or water or any gas or liquid in the body). In this project the model is designed with respect to all the available constraints using an advanced cad softwares like Creo parametric, solid works, catia and solid edge. Later the product file is converted to “.STP” file format (standard exchange of product file) and imported to ansys workbench to find deformation and analytic valve with respect to the model or product definitions. In this project the product was undergone various types of analysis to find frequencies with respect to gravity or mass by using Modal analysis and by Using static structural analysis total deformation, stress and strain valve, product life and failures etc., can be calculate by using Ansys workbench. Ansys software helps to find the accurate or approximate solutions
