Numerical Investigation of Turbine Blade Trailing Edge Flow Ejection Effects on Mach Number Distribution of Gas Turbine Blade Surface, Using RNG.k-ε Turbulance Model

In this research, the turbine blade trailing edge flow ejection effects on Mach number distribution hasbeen analyzed. For flow analysis RNG.K-ε turbulence model was used and the results as Machnumber distribution on the blade surface was compared with experimental data. This comparisonshows that the precision of the mentioned model for analyzing the Mach number loss at the trailingedge is due to the vortex which is generated there. The results also show the trailing edge flow ejectioneffects on blade surface Mach number distribution.
