We study the Joule-Thomson expansion in Einstein-Maxwell theory supplemented with so-called quasitopological electromagnetism, this extended phase space thermodynamic approach. compute coefficient and depict all relevant inversion isenthalpic curves temperature-pressure plane, determining manner corresponding cooling heating regions. In contrast previous related works we show existence of three...

We investigate the Joule-Thomson effect of AdS black holes in conformal gravity. derive coefficient terms thermodynamic relations and then make an alternative derivation via a direct way. analyze find that coefficients obtained from two different approaches are equal. Moreover, we present novel isenthalpic process which inversion temperature is minimal it separates corresponding heating-cooling...

This paper investigates thermoelectric interface demarcation during directional solidi cation of Bismuth with varying gravitationally-dependent buoyancy convection. A physicsbased computer model is developed in which gravitational, thermoelectric and magnetohydrodynamic e ects are included. To help design our ongoing experimental tests, numerical simulations of directional solidi cation in a Br...

The gas lift in the offshore M field will be performed with high CO2-content associated gas, but change of wellbore temperature and pressure during injection process lead to phase physical parameters which has a great impact on design lift. To ensure smooth implementation field, this paper conducts study considering CO2 state. We obtained density, viscosity, compression factor, constant specifi...

The one-dimensional flow of a fluid near saturation through a micro-porous membrane is considered. Upstream of the porous membrane the fluid is in a state of saturated vapor. Downstream, the fluid is in a state of unsaturated vapor. Due to the Joule-Thomson effect, the fluid is cooler at the downstream side of the membrane than at the upstream side. Due to the temperature difference and the hea...
