Abstract
Designers of cryostable superconducting magnets, which operate in pool boiling He I, are aware of critical heat flux densities. The regions of most general interest are the peak nucleate boiling and recovery heat fluxes at a conductor temperature no more than a few hundred millikelvin above the pool temperature. Systems which depend on nucleate boiling can face a convective region prior to the nucleate boiling transition. Thermal fluctuations can easily effect the pressure to an extent where the liquid becomes subcooled. Depending on the degree of subcooling the temperature difference at the transition to nucleate boiling, can exceed the temperature difference in all of the nucleate boiling region.
