Parametric analysis of the heat transfer in impimging jets

Abstract

Paper presented to the 10th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Florida, 14-16 July 2014.

The paper shows how a phenomenological model can be constructed to develop a simulator that furnishes the dynamic and thermal properties of impinging jets in real time. The presented correlations cover a large range of flow conditions, are based on eleven different experimental data sets and furnish predictions for the local pressure distribution, mean velocity distribution, wall shear stress, temperature distribution and Nusselt number. The analysis considers that the flow properties can be determined in terms of gross parameters like the free-jet momentum flux, the free-jet heat flux per unit length and the wall heat flux.
