Distribution of Temperatures over a Spherical Heater Placed in He-II
RÉSUMÉ
The results of calculations of the distribution of temperatures in a spherical heater, which is intended for studying film boiling of He-II [1], and the corresponding experimental data are presented. The construction of the spherical heater is described, and the method to calculate characteristic temperatures in it for both boiling of helium II and direct contact of He-II and the heater surface is given. Based on experimentally measured dependences of temperatures and data of video recording, a comparison with the temperature values calculated by the proposed method is carried out. In analyzing heat transfer through the vapor film, relations are used that take into account the nonequilibrium state of transfer processes on interphase surfaces.
