Simulation of temperature distribution in gas turbine stator blade subjected to different internal coolant gases

Abstract

in order to simulate the cooling process and the temperature distribution. At first, the air is applied and the results show a good agreement with previous literature then the other coolants compare their results with the air. The results show that the Helium affects the cooling process strongly and it cools the blade to safer limits rather than air by about 50%, but it increases von Mises stress by about 71% in comparison with air. The two other coolants also have a good and effective cooling performance, but they almost show an identical performance.
