Subcooled pool boiling using a copper heating surface coated with plating metal

Abstract

Microbubble emission boiling (MEB), which is observed in high subcooling temperature condition, is a promising technology because the maximum heat flux of MEB is higher than that of ordinary critical heat flux (CHF). Copper heating surfaces have been typically used in MEB researches. However, the MEB characteristics with plating metal surface is not cleared. Therefore, in this study, subcooled pool boiling using a copper heating surface coated with plating metal was examined. The experimental result found that the MEB characteristics is affected by the material of plating metal.
