in the present work, we have examined the ability of some different equations of state in predicting the joule-thomson coefficient, ?j-t, of different fluids. for dense fluids, for which density is greater than the boyle density, ?b, two appropriate equations of state, namely the linear isotherm regularity, lir, and the dense system equation of state, dseos, have been examined. the results show...

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...

Abstract In this paper, the Joule-Thomson expansion of Born-Infeld AdS black holes is studied in extended phase space, where cosmological constant identified with pressure. The coefficient, inversion curves and isenthalpic are discussed detail using a 4-dimensional hole. critical point hole depicted varying parameter charge Q . T-P plane, temperature obtained different We fi...

Wellbores in Enhanced Geothermal System extends several kilometers from the ground surface, providing large heat transfer areas between the flowing fluid and the surrounding formations. Various techniques and approximations to model wellbore heat transfer have been presented in the literature. Most of the wellbore simulators assume steady one-dimensional flowing without considering heat transfe...

In this paper, we study the Joule–Thomson expansion of torus-like black hole in extended phase space, where cosmological constant is determined by pressure. It noteworthy that has a horizon toroidal topology, rather than spherical topology. We both inversion and isenthalpic curves holes $$T-P$$ plane find their intersection coincides with point distinguishes heat cooling process. Compared to Va...

Many different devices and cycle arrangements can be used in part.ially cooling gas for helium liquefaction . With the exception of the Simon freeexpansion type liquefier , howeverwhich is suitable only for small-yield, batch productionall uch arrangements have a final stage at the lowest temperatures, in which a so-called Joule-Thomson proces takes place. This process may be considered to incl...
