A correlation based on the general form of cubic equations of state has been derived. This equation provides a convenient mathematical form of the Joule-Thomson coefficient in terms of the state variable V and T. The Joule-Thomson coefficient calculated by this correlation has been compared with experimental data. It has been shown that the Redilich-Kwang equation of state is a suitable equ...

Progress in the synthesis of semiconductor nanowires (NWs) has prompted intensive inquiry into understanding the science of their growth mechanisms and ultimately the technological applications they promise. We present new results for the size-dependent growth kinetics of Ge NWs and correlate the results with a direct experimental measurement of the Gibbs-Thomson effect, a measured increase in ...

Joule-Thomson cooling systems are used in refrigeration and liquefaction processes. There are extensive studies on Joule-Thomson cryogenic systems, but most of them coverage steady state conditions or lack from experimental data. In the present work, transient thermal behavior of Joule-Thomson cooling system including counter current helically coiled tube in tube heat exchanger, expansion valve...

The influences of droplet size on the growth of self-catalyzed ternary nanowires (NWs) were studied using GaAsP NWs. The size-induced Gibbs-Thomson (GT) effect makes the smaller catalytic droplets have lower effective supersaturations and hence slower nucleation rates than the larger ones. Large variation in droplet size thus led to the growth of NWs with low uniformity, while a good size unifo...

Bidie, C.l.is.; P. S. Turnbull, K.H.S.; D. Sinclair, c.s.l ; and G. W. R. Hay; Colonels W. P. Warburton, C.S.I.; and A. Stephen ; Brigade-Surgeons G. G. Maclaren, J. Robb and J. Arno...

The rapid deformation of liquid and solid materials usually results in temperature changes. This rapid deformation is considered to be a nearly adiabatic process where the heat generated during the deformation changes the temperature of the material. Early experiments showed that metals cooled down on sudden stretching and warmed up upon compression [1]. In 1805, Gough [2] observed that the tem...

The Seebeck and Peltier effects have been widely studied used in various thermoelectric technologies, including thermal energy harvesting solid-state heat pumps. However, basic applied studies on the Thomson effect, another fundamental effect conductors, are limited despite fact that allows electronic cooling through application of a temperature gradient bias rather than construction junction s...
