Aerodynamic Losses in Turbines with and without Film Cooling, as Influenced by Mainstream Turbulence, Surface Roughness, Airfoil Shape, and Mach Number
Figure 15
Profiles measured at one axial chord length downstream of the cambered vane for [38]. (a) Normalized local total pressure losses. (b) Normalized local Mach numbers. (c) Normalized local kinetic energy. (d) total pressure loss coefficient.
