Enhancement of Pool-Boiling Critical Heat Flux with Structure Focused on Liquid Film Retention Function

Abstract

Boiling is used for high heat flux devices because of its high heat transfer coefficient. The critical heat flux (CHF) is known as the coolability limit since it is the threshold value at which the boiling transition occurs. Due to the industrial demands, systematic approaches are required to investigate CHF enhancement. Therefore, We set metal mesh seat on the heat transfer surface, and conducted pool boiling experiments with liquid film retention structure. We demonstrated CHF enhancement with those structures and discussed the relationship between structural parameters and CHF enhancement effect.
