Aerodynamic Losses in Turbines with and without Film Cooling, as Influenced by Mainstream Turbulence, Surface Roughness, Airfoil Shape, and Mach Number
Figure 7
For , comparison of normalized Integrated Aerodynamic Loss as dependent upon the exit Reynolds number for the smooth airfoil (), the airfoil with small roughness (), and the airfoil with large roughness () for the symmetric airfoil investigations [8].
