Phase Behavior of a Cell Fluid Model with Modified Morse Potential
2020
The present manuscript gives a theoretical description of the first-order phase transition in a cell fluid model with a modified Morse potential and additional repulsive interaction. In the framework of the grand canonical ensemble, the equation of state of the system in terms of chemical potential-temperature and terms of density-temperature is calculated for a wide range of density and temperature. The behavior of the chemical potential as a function of temperature and density is investigated. The maximum and minimum admissible values of the chemical potential, which approach each other with decreasing temperature, are exhibited. The existence of a liquid-gas phase transition in a limited temperature range below the critical $T_c$ is established.
