Joule–Thomson expansion for a nonlinearly charged Anti-de Sitter black hole

Abstract

In this work, we examine the Joule–Thomson (JT) expansion for a nonlinearly charged AdS black hole solution. We obtain the expression of the JT coefficient from which we calculate the inversion temperature for numerous values of the charge [Formula: see text]. Moreover, we derive the isenthalpic curve in [Formula: see text] diagram and illustrate the cooling–heating region by the inversion curve for fixed masses. We find that the temperature and pressure on the inversion point decrease with a larger charge [Formula: see text] and increase as the black hole mass grows.
