Abstract

The results of model calculation of superfluid helium boiling under microgravity conditions are reported. The evolution of a vapour film on the cylindrical heater surface inside the porous thickwalled structure is analyzed. The molecular-kinetic theory methods are used to describe heatand mass-transfer within helium interface. The equation of vapour-liquid interface motion is solved. The effect of experimental parameters on the vapour film properties is studied. The calculation data for microgravity and terrestrial conditions are compared.
