Dynamics of the rotational degrees of freedom in a supercooled liquid of diatomic molecules [PDF]

Physical Review E, 1997
Using molecular dynamics computer simulations, we investigate the dynamics of the rotational degrees of freedom in a supercooled system composed of rigid, diatomic molecules. The interaction between the molecules is given by the sum of interaction-site potentials of the Lennard-Jones type.

Influence of Ultrasonic Vibration on Degree of Supercooling of Disodium Hydrogenphosphate Dodecahydrate.

Journal of the Japan Institute of Energy, 2002
The influence of ultrasonic vibration on the degree of supercooling was investigated for disodium hydrogenphosphate dodecahydrate, which is used in longterm, supercooled thermal energy storage (Super-TES). Super-TES stores thermal energy at temperatures lower than the melting point of the phase-change material, which reduces heat loss from the storage ...

On the freezing process with supercooling. Measurements of the heat transfer surface effects on the maximum degree of supercooling, and the statistical analyses.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1988
Basic experiments and statistical analysis were performed concerning the effects of cooling surface properties on the degree of supercooling. In experiments, pure water layers were cooled from the top by five kinds of copper cooling surfaces (electrolytic polished, buffed, gold-plated, nickel-plated and porous copper disks) under various cooling rates,
