Résumé

In this study, the heat transfer process was investigated utilizing a three-dimensional finite volume numerical method and renormalization group (RNG) theory based on a turbulence model. The issuing incompressible jet impinges upon the inside of an inclined surface, creating a thermal boundary layer and a fully three-dimensional vortex structure. Numerical analyses predict a detailed description of fluid flow patterns and heat transfer coefficients. Experimental investigations were performed for further validation of the numerical result. The effect of different turbulence levels in the numerical solution is reported.
