SUPPRESSION OF OSCILLATIONS OF THE VAPOR-LIQUID PHASE BOUNDARY IN BOILING OF SUPERFLUID HELIUM INSIDE A POROUS BODY

摘要

This work seeks to investigate the processes of boiling of helium-II on the heater surface under various conditions. The task of determining dynamic characteristics in the process of evolution of the vapor film on the surface of a cylindrical heater in the presence of a confining coaxial porous structure is set. The processes in a free volume and under constrained conditions are compared. The existing experimental data on the boiling of helium-II on the sphere surface are analyzed. The results of video filming of the boiling of superfluid helium under zero-gravity conditions on the surface of a thin wire are interpreted.
