Quantification of Cooled Film Thermal Protection Using Net Heat Flux Reduction within Transonic Environments

Considered are NHFR or net heat flux reduction data in order to illustrate and quantify turbulent thermal convection phenomena within a unique and intricate cooled film environment along the extremity end of a transonic turbine airfoil with a rim in the form of a squealer. Of particular focus are th...
