Spatially resolved heat transfer measurements have been made on a nominally isothermal surface that is spray cooled. The effects of dissolved gas and subcooling were studied. The local measurements were obtained using a microheater array with ninety-six heaters each about 700 microns in size. The heater array consisted of thin-film platinum resistors deposited on a quartz substrate. Electronic feedback circuits were used to keep each of the heaters at a constant temperature and the voltage required to do this was measured. The array was cooled with FC-72 using a spray nozzle from ISR. The heat transfer data was correlated with high-speed images of the flow structure obtained from below. In this paper, heat transfer mechanisms in spray cooling will be discussed, with a particular emphasis on the effects of a non-condensable gas on critical heat flux in comparison to the comparable effects of thermally subcooling the liquid prior to atomization.
