Aerodynamic Losses in Turbines with and without Film Cooling, as Influenced by Mainstream Turbulence, Surface Roughness, Airfoil Shape, and Mach Number

<table>Overall exergy destruction as it varies with film cooling blowing ratio as measured one axial chord length downstream of different smooth airfoils with different exit Mach numbers, and different film cooling configurations and conditions.</table>
