Thermal Analysis of a Steam Turbine Blade

Abstract

 Steam turbine is an excellent prime mover to convert heat energy of steam to mechanical energy. Of all heat engines and prime movers the steam turbine is nearest to the best and it is widely used in power plants and in all industries where power is needed for process. In power generation mostly steam turbine is used because of its greater thermal efficiency and higher power-to-weight ratio. Because the turbine generates rotary motion, it is particularly suited to be used to drive an electrical generator–about 80% of all electricity generation in the world is by use of steam turbines. In this project we are going to design a propeller blade assembly in Catia V5 R21 and thermal analysis is done in Ansys. In order to evaluate the effectiveness of composites and metal propeller using FEA packaged (ANSYS). Thermal analysis is performed on both Aluminum and composite propeller to find out the heat flux and thermal error.
