Mechanism of heat transfer in vacuum superinsulation

  • Published:
Journal of engineering physics Aims and scope

Abstract

This paper shows that the experimentally observed point of inflection on the temperature curve in vacuum superinsulatlon is due to the nonuniform residual gas pressure in the layers and the significant contribution of the gas conductivity to the total heat transfer.
