Pool boiling heat transfer experiments from a platinum wire healer in FC-72 liquid were conducted under terrestrial and microgravity conditions, both with and without the presence of a high intensity acoustic standing wave within the fluid. The purpose of this research was to determine the effects of an acoustic sound field on nucleate pool boiling in both terrestrial gravity and microgravity. The platinum wire heater was used as a constant heat flux source and as a thermometer. The effects of acoustics on heat transfer were measured by the change in the average surface temperature of the heater. In terrestrial gravity a partial boiling curve was established with and without acoustics. In general, it was found that both the natural convection and boiling heat transfer rates were increased with the presence of an acoustic standing wave in terrestrial gravity. The highest heat transfer augmentation was registered when the heater wire was placed at the acoustic pressure antinode. In microgravity, the acoustic force was shown to be a promising means in maintaining nucleate boiling.
