Influence of gravity on pool boiling on a flat plate: Results of parabolic flights and ground experiments

Experiments of pool boiling of HFE7000 on a flat plate have been performed in both earth and microgravity conditions in parabolic flights. The effects of pressure, subcooling and gravity are studied. Experiments show that in fully developed boiling regime gravity and subcooling have a weak influence on heat transfer. By identifying mechanisms that control heat transfer, the weak influences of gravity and subcooling are explained.
