B216 Improvement of Heat Transfer by Radiation Catalyst : 2nd Report, Leidenfrost Temperature and Critical Heat Flux

Abstract

Improvement of CHF requires that the cooling liquid can contact the heating surface, or a high- wettability heating surface, even if a vapor bubble layer is generated on the surface. From this point of view, an experimental study to investigate CHF was performed by use of an oxide semiconductor-coated material under a γ ray irradiation environment. The results showed that CHF of oxidized titanium was improved up to 100% after SOOkGy ^<60>Co γ ray irradiated.
