Abstract

In this paper, the charged acoustic black hole with a cosmological constant has been assumed. We have taken into account the negative cosmological constant as thermodynamic pressure in the extended phase space. Then we derived the thermodynamic quantities and investigated their behavior. We have studied the critical values of temperature and pressure. By calculating the specific heat capacity, we have analyzed the thermal stability of the charged acoustic black hole. Then we studied the heat engine phenomena of the black hole. We discovered the Carnot engine’s efficiency and the brand-new engine phenomenon of the black hole.
