Heat transfer between a room temperature, turbulent round jet and a segmented flat plate perpendicular to it has been investigated.
The heat transfer surface consisted of invar rings insulated from each other with silicone rubber. The source of heat was steam at atmospheric pressure condensing on the back of the heat transfer surface.
Since data were taken over a wide range of vertical distances between the nozzle and the flat surface both the potential cone and the fully developed regions of the jet were observed interacting with the heated plate.
It was determined that two modes of heat transfer occur; one in the potential cone region and the other in the fully developed region of the jet striking the plate. Results were successfully correlated at the stagnation point for all vertical distances between the jet and the plate. The decrease in heat transfer coefficient with increasing radial distance from the stagnation point has been successfully correlated in both the potential cone and the fully developed regions of the jet as well.
