Abstract

The present work is devoted to the numerical study of the interaction of an inclined plane turbulent jet with a moving horizontal isothermal hot wall. The inclination of the jet allows the control of the stagnation point location. Numerical predictions based on statistical modeling are obtained using a second order Reynolds stress turbulence model coupled to an enhanced wall treatment. For a given impinging distance H (H =8e), the considered problem parameters are: (a) jet exit Reynolds number (Re, based on the thickness "e" of the nozzle) in the range from 10000 to 25000, (b) surface-to-jet velocity ratio Rsj from left to right; ranging between 0 and 1.75 and (c) optimal inclination angle of the jet between 0° to 25°. The calculations are in good agreement with the available data. The numerical results show that the heat transfer is greatly influenced by the velocities of the jet and the moving wall. In particular, the local Nusselt number decreases with increasing surface-to-jet velocity ratios (until Rsj=1). Optimal inclination of the jet can be used to enhance heat transfer and modify the stagnation point location. The distribution of average Nusselt number is correlated with typical problem parameters.
