A steam turbine is a device that extracts thermal energy from pressurized steam and uses it to do mechanical
work on a rotating output shaft. The steam turbine gives the better thermodynamic efficiency by using multiple stages in
the expansion of steam. The stages are characterized by the way of energy extraction from them is considered as impulse
or reaction turbines. In this work the parameters of steam turbine blade varied and analysis is done for strength, life and
heat transfer rates. The varied parameters are the ratio of X-axis distance of blade profile by chord length and ratio of
maximum height of blade profile in Y-direction to the chord length. The 3D modeling is done by using catia software.
The ANSYS software is used for static, thermal analysis, finally concluded the suitable design and material (Haste alloy,
Chrome steel, Inconel 600) for steam turbine blade, after steam turbine blade imported the stl file 1:2 ratio in to 3d
printing we done rapid prototyping method.
