Wepresent a revised formof the energy balance for the coupled thermodynamics of liquid water flowing in porousmedia and give examples of situations where a commonly used formulation based on transport of enthalpy leads to erroneous results. Assuming negligible contribution from kinetic energy as well as sources and sinks such as energy from radioactive decay, total energy conservation is reduce...

The process of the Joule–Thomson adiabatic expansion within rational NED (RNED)-AdS spacetime is investigated. isenthalpic $$P{-}T$$ diagrams and inversion temperature are depicted. depends on magnetic charge RNED coupling constant black holes. When coefficient vanishes, a cooling-heating phase transition occurs. We consider cosmological as thermodynamic pressure, hole mass treated chemical ent...

joule-thomson cooling systems are used in refrigeration processes such as cryogenic gas liquefaction. although extensive studies have been carried out by researchers, most of them include cryogenic heat exchangers and their associated fields. in the current study, an attempt was made to indicate the effect of using inappropriate operational conditions in a cryogenic joule-thomson cooling system...

In this paper, we have considered the heat engine and Joule–Thomson expansion for charged AdS black hole in context of nonlinear electrodynamics massive gravity. For engine, obtained analytical expression efficiency terms either entropies or temperatures pressures various limits. hole, derived isenthalpic curves $$T{-}P$$ diagram, coefficient, inversion curves. We also indicated detail effects ...

In this work, the influences of the Thomson effect and the geometry of the p-type segmented leg on the performance of a segmented thermoelectric microcooler (STEMC) were examined. The effects of geometry and the material configuration of the p-type segmented leg on the cooling power (Qc) and coefficient of performance (COP) were investigated. The influence of the cross-sectional area ratio of t...

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...

Caledonian United Service Club, Edinburgh, on the evening of Friday, May 28th, Sir Alexander Christison,#ar?.,the senior member of the service, presided, and the following officers were present: Surgeon-Generals G. 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...

one whose clinical acumen, painstaking and accurate observations and valuable writings had gained for him a reputation which was world-wide and which added a lustre to British Medicine. John Thomson was born in Edinburgh in 1856, and, after receiving his education at the Academy and University, he studied in London, Berlin and Vienna. His interest was early directed towards diseases of children...

Herein, we extend Joule-Thomson expansion to the low-dimensional regime by considering rotating Ba\~nados-Teitelboim-Zanelli (BTZ) metric in ($2+1$)-dimensional space-time. Specifically, properties of three important aspects expansion, including coefficient, inversion curve, and isenthalpic curve were studied. The divergence point coefficient zero Hawking temperature investigated. curves $T--P$...
