Abstract

The processes of heat and mass transfer during the flow of helium-II (He-II) in a channel with porous backfilling placed in a particular section of its length are studied. Heat flux is directed along the axis of the channel in such a way that on one side of the backfilling vapor plug is formed. Calculation of steady-state transport processes at vapor-He-II interfaces is carried out using methods of molecular-kinetic theory. The normal fluid flow in the pores in laminar and turbulent regimes is described by equations taking into account features of heat and mass transfer in superfluid helium. The relationships between the length of the porous insert and the velocities of fluids for different flow regimes are formulated. The results of the calculations are analyzed by comparison with previous data for the flow of He-II in the individual capillary.
