β¦ Synopsis
Analytical and experimental studies of heat transport to forced flow He II are reported. The work is pertinent to the transfer of He II in space. An analytical model has been developed which establishes a condition for two phase flow to occur in the transfer line. This condition sets an allowable limit to the heat leak into the transfer line. Experimental measurements of pressure drop and flow meter performances indicate that turbulent He II can be analysed in terms of classical pressure drop correlations.

Numerical analysis is performed with the two-fluid model and the simplified model of Kashani et al. to study one-dimensional forced convection heat transfer of He II in a pipe heated at the midpoint along its length. An entropy transport equation derived from the theory of Khalatn~tkov is incorporat
The Gorter-Mellink equation of steady-state heat transfer in He II is used to develop a method of calculating the peak heat flux for a magnet cooled in a bath of He II. It is shown that the equivalent thermal resistance of a series or parallel arrangement of linear cooling channels is given by ReQ =
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
