Heat transport measurements in a large diameter tube containing He II are reported. The range of temperatures investigated are from 1.7K to 2. 1K with applied pressures up to the critical pressure, 0.23MPa. Temperature gradients established in the liquid are compared with previous experimental work

Heat transport through He II is summarized in terms of the hydrodynamics of the two-fluid model. With increasing thermal flux, three regimes are identified, depending on the development of vorticity in the superfluid component and the development of a classical turbulence in the normal component. Ca
Kapitza conductance in steady and transient boiling heat transfer on a horizontal 0.2mm diameter test wire was estimated based on the measured Kapitza conductance value for the same surface in He II. The He II experiments performed are for liquid temperatures ranging from 1.8 to 2.1 K under atmosphe
