Heat transfer between an axisymmetric jet and a plate held normal to the flow

Heat transfer between a submerged jet of water and a flat surface held normal to the flow was studied experimentally over a wide range of plate to nozzle diameter ratios (8 ? D/d < 58). The average heat transfer coefficients were found to be independent of nozzle to plate distance (γ) in the region studied, (γ/d < 7). An equation was developed by separating the target area into the impingement and the wall jet regions. The data were correlated by For nozzle Reynolds numbers 2,000 to 40,000; D/d ? 8 and γ/d < 7.
