Simulating Cooling Injection Effect of Trailing Edge of Gas Turbine Blade on Surface Mach Number Distribution of Blade

In this research, a gas turbine blade cascade was investigated. Flow analysis around the blade was conducted using RSM and RNG.K-ε turbulence modeling and it is simulated by Fluent software. The results were considered for the cases as Mach number loss at the trailing edge of blade caused by vortexes that were generated at the end of blade. Effect of cooling flow through the trailing edge on th...

Turbine Blade Tip Cooling and Heat Transfer

ii ACKNOWLEDGEMENTS Behind every success, there is inspiration or support of at least one person. In my case, it was a group of people including my mentor, my family, and my friends. First of all, I would like to thank Dr. Srinath Ekkad for his guidance, wisdom, and financial support. I do not think many advisors would go to the lab to help his student running an experiment. Whenever I had any ...

Optimization of turbine blade cooling with the aim of overall turbine performance enhancement

In the current work, different methods for optimization of turbine blade internal cooling are investigated, to achieve higher cyclic efficiency and output power for a typical gas turbine. A simple two-dimensional model of C3X blade is simulated and validated with available experimental data. The optimization process is performed on this model with two different methods. The first method is ...

Draft Gt2003-38118 Experimental and Numerical Investigation of Impingement on a Rib-roughened Leading-edge Wall

Leading edge cooling cavities in modern gas turbine airfoils play an important role in maintaining the leading edge temperature at levels consistent with airfoil design life. These cavities often have a complex cross-sectional shape to be compatible with the external contour of the blade at the leading edge. Furthermore, to enhance the heat transfer coefficient in these cavities, they are often...
