ABSTRAKT

The design of efficient cryogenic and refrigerating equipment relies on the knowledge of heat and mass transfer coefficients as well as of the thermophysical properties of materials in various working conditions.
The Symposium addressed the problems of heat and mass transfer in a very wide range of temperatures, from 400 K to the fascinating region of the mK, at the meeting point of thermodynamics, transport processes and technology.
The following topics were discussed: thermal insulation, heat and mass transfer in pute refrigerants and mixtures, thermodynamics and thermophysical properties, freezing and melting , heat and mass transfer at very low temperature, and cooling of supraconducting devices.
In the field of super insulation, Prof. Tien discussed anomalous conduction and thermal radiation phenomena occurring when the mean free path of phonons or electrons is of the same order of magnitude as the characteristic length of the material, for instance in cryogenic multilayer insulation or microsphere packing.
Some papers dealt with interesting results concerning classical insulants: the connection between thermal properties and structure, the calculation of heat transfer in complex systems and methods for measuring transport properties.
