Summary
A brief discussion of heat transport phenomena in He II at low fluxes precedes examination of heat transport at or near the maximum. The two-fluid model is used in treating subcritical heat flow and frictional and resistance terms are added for the supercritical fiow. Solutions for subcritical capillary flow and flow through a slit are compared with experimental results. For the case of the maximum heat flux, nucleate boiling and formation of gaseous films between the heater surface and fluid are examined. Heat convection is explored, and the effects of bubble formation are discussed. Experimental results on nucleate boiling and the formation of He I--He II boundaries are described. Comments on transient operation are included. Maximum flux in He II is noted to be an order of magnitude greater than for He I and the heat transfer coefficient below the lambda point is found to be similar for the two fluids. 38 references.
