Magnetically charged AdS black holes and Joule-Thomson expansion

Abstract

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