Heat flux through a phase interface in superfluid helium
The possibility of using superfluid helium as a coolant in cryogenic systems has been discussed recently. Heat transfer with this medium is realized quite uniquely in the film nucleation mode. In one of the classical papers, helium boiling on a cylinder and vertical plate was studied by using a boundary-layer approximation in a vapor film. The role of the superfluid helium was reduced to the fact that it regulated the heat flux, transferred from the phase interface to the free surface. This quantity, denoted as /sub qB/ (T /sub B/, H) was the parameter of the classical theory, and not calculated. In this work the heat flux between phases is calculated as a function of the degree of submersion and the temperature of the bath on the basis of solution of the hydrodynamic problem for superfluid helium.
