Abstract

The heat transfer components and inner wall temp. profiles of a cylindrical, cryogenic glass dewar was studied as a function of the liq. $N_2$ level in the dewar. The study shows that the gas conduction heat transfer is further enhanced with the fall of liq. level in the dewar, due to increase in interspace gas pressure. A simple analysis based on R. J. Corruccini's (1959) gas conduction equation is presented for the explanation of the obsd. gas conduction heat transfer. The inner wall temps. are nearly linear, except in the regions close to the liquid surface.
