“…For charged AdS black holes [57] and Kerr-AdS black holes [58], the isenthalpy expansion process and the inversion curve are investigated. Then the works are generalized to quintessence charged AdS black holes [59], holographic superfluids [60], charged AdS black holes in f(R) gravity [61], AdS black hole with a global monopole [62] and AdS black holes in Lovelock gravity [63]. The results show that the inversion curvesT (P ) for all the above black hole systems have only positive slope.…”

Joule-Thomson expansion process is studied for charged Gauss-Bonnet black holes in AdS space. Firstly, in five-dimensional space-time, the isenthalpic curve in T − P graph is obtained and the cooling-heating region is determined. Secondly, the explicit expression of Joule-Thomson coefficient is obtained from the basic formulas of enthalpy and temperature. Our methods can also be applied to van der Waals system as well as other black hole systems. And the inversion curveT (P ) which separates the cooling region and heating region is obtained and investigated. Thirdly, interesting dependence of the inversion curves on the charge (Q) and the Gauss-Bonnet parameter (α) is revealed. InT −P graph, the cooling region decreases with charge, but increases with the Gauss-Bonnet parameter. Fourthly, by applying our methods, the Joule-Thomson expansion process for α = 0 case in four dimension is studied, where the Gauss-Bonnet AdS black hole degenerates into RN-AdS black hole. The inversion curves for van der Waals systems consist of two parts. One has positive slope, while the other has negative slope. However, for black hole systems, the slopes of the inversion curves are always positive, which seems to be a universal feature. *

Joule-Thomson Expansion of the Quasitopological Black Holes

In this paper, we investigate the thermal stability and Joule-Thomson expansion of some new quasitopological black hole solutions. We first study the higher-dimensional static quasitopological black hole solutions in the presence of Born-Infeld, exponential, and logarithmic nonlinear electrodynamics. The stable regions of these solutions are independent of the types of the nonlinear electrodynamics. The solutions with horizons relating to the positive constant curvature, k=+1, have a larger region in thermal stability, if we choose positive quasitopological coefficients, μi>0. We also review the power Maxwell quasitopological black hole. We then obtain the five-dimensional Yang-Mills quasitopological black hole solution and compare it with the quasitopological Maxwell solution. For large values of the electric charge, q, and the Yang-Mills charge, e, we showed that the stable range of the Maxwell quasitopological black hole is larger than the Yang-Mills one. This is while thermal stability for small charges has the same behavior for these black holes. Thereafter, we obtain the thermodynamic quantities for these solutions and then study the Joule-Thomson expansion. We consider the temperature changes in an isenthalpic process during this expansion. The obtained results show that the inversion curves can divide the isenthalpic ones into two parts in the inversion pressure, Pi. For P<Pi, a cooling phenomenon with positive slope happens in T−P diagram, while there is a heating process with a negative slope for P>Pi. As the values of the nonlinear parameter, β, the electric and Yang-Mills charges decrease, the temperature goes to zero with a small slope and so the heating phenomena happens slowly.

“…In classical thermodynamics, Joule-Thomson expansion is an enthalpy process, which refers to the process of gas expansion from high pressure to low pressure through a porous plug. Subsequently, this creative work has been extended to various black holes, such as typical RN-AdS black holes [47], d-dimensional charged AdS black holes [48], Kerr-AdS black holes [49], f (R) gravitational charged AdS black holes [50], the AdS black hole with a global monopole [51], the conventional (Bardeen)-AdS black hole [52], the charged AdS black hole in rainbow gravity [53], the Hayward-AdS black hole [54], the AdS black hole with momentum relaxation [55], the Holographic superfluid [56], the RN-AdS black hole immersed in perfect fluid dark matter [57], Gauss-Bonnet black holes [58], the Quasitopological Black Holes [59], and other space-times . The inversion curves and isenthalpic curves in the P − V plane are given.…”

In this paper, we study the Joule-Thomson expansion of the torus-like black hole in extended phase space, where the cosmological constant is determined by the pressure. It is noteworthy that the torus-like black hole has a horizon of toroidal topology, rather than a horizon of spherical topology. We study both the inversion and isenthalpic curves of the torus-like black holes in the T − P plane and find that their intersection coincides with the inversion point that distinguishes the heat in the cooling process. Compared to the Van der Waals fluid, the inversion curves of torus-like black holes do not end at any point and only lower inversion curves are available. Most importantly, we find that the P − V diagram of the torus-like black hole has no inflection point, i.e., the torus-like black hole is always thermally stable. Therefore, the torus-like black hole has no critical point and critical temperature, and there is no ratio between the minimum inversion temperature and the critical temperature.
