Joule-Thomson Expansion of RN-AdS Black Hole Immersed in Perfect Fluid Dark Matter

Understand

In this paper, we study the Joule-Thomson expansion for RN-AdS black holes immersed in perfect fluid dark matter.

• Firstly, the negative cosmological constant could be interpreted as thermodynamic pressure and its conjugate quantity with the volume gave us more physical insights into the black hole.
• We derive the thermodynamic definitions and study the critical behaviour of this black hole.
• Secondly, the explicit expression of Joule-Thomson coefficient is obtained from the basic formulas of enthalpy and temperature.
