โฆ Synopsis
Measurements have been made of the temperature of the mner wall of a glass experimental cryogenic dewar as a function of the dmtance above the surface of the hquM hehum For a normal hquM hehum bath these results can be fitted by a simple model assuming thermal equthbrtum to exist between the walls and the rising gas evolved by evaporation. Measurements were also made above a superflutd bath and using two dewar configurations.

Significant radial profiles of concentration and temperature may exist in packed bed adsorbers, leading to a different breakthrough behavior at the wall than in the core of the bed. Respective data have been gained by near-infrared tomography for zeolite and water in relatively narrow tubes, and are
