Mechanism of nucleate pool boiling heat transfer to sodium and the criterion for stable boiling [PDF]

open access: yes, 1967
A comparison between liquid metals and other common fluids, like water, is made as regards to the various stages of nucleate pool boiling. It is suggested that for liquid metals the stage of building the thermal layer plays the most significant part in ...
