Abstract

In this paper we study Joule-Thomson (JT)(JT) expansion of non-linearly charged AdSAdS black holes in Einstein-power-Yang-Mills (EPYM) gravity in DD dimensions. Within the framework of extended phase space thermodynamics we identify the cosmological constant as thermodynamic pressure and the black hole mass with the enthalpy and derive the Joule-Thomson coefficient μ\mu. Furthermore we have presented equations for inversion curves and the exact expression for the minimum inversion temperature. We also have calculated the ratio between the minimum of inversion TiminT_i^{min} and the critical temperature TcT_c and obtained the analytic expression for the ratio TiminTc\frac{T_i^{min}}{T_c} that depends explicitly on the non-linearity parameter qq and dimension DD. We consider the isenthalpic curves in the TPT- P plane for different values of the fixed black hole mass and obtain heating and cooling region. Finally we have dealt with two limiting masses which characterizes the process of Joule-Thomson expansion in the EPYMEPYM black holes.
