The Vapor Film Evolution at Superfluid Helium Boiling in Conditions of Microgravity

The results of numerical modeling of the vapor film temporal evolution on the cylindrical heater at film boiling of the superfluid helium (HeII) in conditions of microgravity are presented. The methods of molecular-kinetic theory have been applied to describe the vapor near the interface: vapor-HeII. For this purpose the Boltzmann equation have been solved. The system of equations of conservation for the liquid has been used. Different models of heat transfer in superfluid helium have been discussed and studied.
