Abstract
An experimental study on the boiling heat transfer characteristics of liquid films flowing downward along vertically positioned plane and constant curvature surface (CCS) with isolated fine cavities was conducted. The effects of structural surfaces were examined, comparing with the case of smooth plane. The main results of these experiments are summarized as follows; (1) In the case of structual plane surface, there are remarkable enhancements of heat transfer rate in the nucleate boiling region. (2) In the case of CCS, it takes large values of heatflux in the region which strongly governed by the surface evaporation. (3)CCS avoids effectively the occurrence of splitting of the liquid film into rivulets. This study aims to put practical use of the heat transfer enhancement for the evaporator of a two-phase closed thermosiphon.
