Cooling of gas turbine blades is of paramount importance in the present technological scenario. Gas turbine blades are subjected to very high temperatures, which are at times above the melting point of the blade material itself. An increase in the inlet temperature of fluid increases the efficiency of the turbine. Therein lies the necessity of cooling the blades to temperatures within the safe operating conditions. Many methods of cooling have been proposed which include internal and external cooling. In this paper, air cooling of stainless steel turbine blades has been investigated with the use of varying geometry of air passages. Model Geometries have been created using SolidWorks Software. The Effectiveness of the design has been analyzed using Finite Element Method software, ANSYS Workbench. Using the Steady State Thermal and Static Structural modules of ANSYS, the effect of varying the air passage geometry on thermal and structural behavior of the blade has been realized on the given model.
