We investigate the thermodynamics of general fluids that have the constriction that their pressure is constant. We first consider the more general thermodynamic properties of this class of fluids finding the important result that for them adiabatic and isothermal processes should coincide. We therefore study their behaviors in curved space-times where local thermal equilibrium can be appealed. Thus, we show that this dark fluid degenerates with the dark sector of the $$\Lambda $$ΛCDM model only… CONTINUE READING
