Summary

An understanding of the phenomena can be beneficial from the perspectives of design and optimization of compact evaporators and condensers such as plate-fin or microgroove heat exchangers. The subject of this study is the nature of flow boiling heat transfer in a confined space when capillary forces determine the flow pattern. This study involves flow boiling of refrigerant R318C in a transparent annulus with a 0.9 mm gap. The heat transfer coefficient and flow pattern are presented both for subcooled and saturated flow boiling. The regimes of nucleate boiling and forced convection were determined as functions of film thickness.
