Appropriateness Investigations on Nimonic 901 and Rane 77 made Guide Vanes of Gas Turbine with Showerhead Cooling

Gas turbines are under the class of high temperature application thermal device. Stability of the material at elevated temperature is difficult to predict conventional methods. The design, engineering offers solution for such cases. The stability can be experimented for such cases using modeling and simulation by means of design engineering softwares. Structural stability of the material depends on the shape, material and load. It is required to analyze the structural stability of such gas turbine components at elevated temperature. The hollow portion like cooling design and greatly influences on the structural stability of them. This research focuses on the material influence on guide vane with showehead type cooling design. The high temperature materials like Nimonic 901 and Rane 77 were considered for this analysis. The Pro E and ANSYS R14 were employed for modelling and FEM analysis respectively.
