BOILING OF HELIUM II ON CYLINDRICAL HEATERS: ANALYSIS OF EXPERIMENTAL OBSERVATIONS FROM THE END SURFACE

The authors have presented experimental data on the boiling of superfl uid helium (helium II) on the surface of a cylindrical heater located in the volume of helium II. Observations of the process of heat and mass transfer in the experimental helium volume were carried out from the end of the cylindrical heater. The formation of a vapor fi lm of fi nite thickness on the surface of the heater on applying thermal load to it, the existence of a noiseless regime of boiling of helium, and the development of oscillations of the phase boundary in its volume have been shown
