DOI: 10.1103/physreve.97.062115http://hdl.handle.net/10400.13/4567The Enskog-Vlasov (EV) equation is a widely used semiphenomenological model of gas-liquid phase transitions. We show that it does not generally conserve energy, although there exists a restriction on its coefficients for which it does. Furthermore, if an energy-preserving version of the EV equation satisfies an H theorem as well, it can be used to rigorously derive the so-called Maxwell construction which determines the parameters of liquid-vapor equilibria. Finally, we show that the EV model provides an accurate description of the thermodynamics of noble fluids, and there exists a version simple enough for use in applications.engEnergy conservationH theoremEnskog-Vlasov equation.Faculdade de Ciências Exatas e da Engenhariajournal article10.1103/PhysRevE.97.062115
