The general class of accelerating, rotating and charged Plebanski-Demianski black holes as heat engine

We first review the general class of accelerating, rotating and charged Plebanski-Demianski (PD) black holes in presence cosmological constant, which includes Kerr-Newman hole Taub-NUT spacetime. assume that thermodynamical pressure may be described by negative so represents anti-de Sitter (AdS) PD hole. The thermodynamic quantities like surface area, entropy, volume, temperature, Gibb's Helmholtz's free energies AdS are obtained due to system. Next, we find critical point corresponding pressure, temperature volume for Due study specific heat capacity, obtain capacity (with constant volume) CV=0 pressure) CP≥0. From this result, conclude stable. examine Joule-Thomson expansion hole, evaluating sign coefficient μ, determine heating cooling nature Putting μ=0, inversion temperature. engine In Carnot cycle, work done its maximum efficiency. Also, describe efficiency a new engine. Finally, analyze Rankine cycle
