Maximum and Minimum Heat Flux in Helium II for a 76.2-μ Diameter Horizontal Wire at Depths of Immersion up to 70 Centimeters
Two regimes of heat transport from a heated surface to liquid He II have been found to exist; a supefluid heat transport regime where the liquid remains in intimate contact with the heated surface and a film boiling regime where the liquid is isolated from the heated surface by the presence of a gaseous film. No one has yet detected in He II the nucleate boiling regime common to all other liquids. Because of the very large thermal conductivity of He II, the heat transport in the first regime takes place at small temperature differences.
