Abstract

Systematic computation studies are conducted to show which physical effects are important and what physical models are required in high-speed film-cooled nozzle flows. Compressibility effects in turbulence models must be accounted for if shear layer spreading and wall heat fluxes are to be correctly predicted. Real gas effects are also quite significant, particularly as they account for widely varying thermochemical property variation because of large static temperature changes typical of nozzle flows.
