| Research Abstract |
In order to disclose the characteristics of vapor film that can exist under high subcooled condition, experiments of pool boiling have been performed using superhydrophobic and PTFE spotted coatings. The results show that the surfaces with PTFE circle dots have higher heat transfer performance in nucleate boiling region and the boiling starts in lower surface superheating. It was also found that by the effect of dissolved periodic gas bubble generation can occur below boiling point.
