Molecular dynamics simulation of liquid-vapor phase equilibrium by using the modified Lennard-Jones potential function

In this paper, the modified Lennard-Jones potential is applied to molecules of liquid argon as well as its vapor and platinum as solid surface in order to perform a molecular dynamics simulation. The system included two groups of molecules: one was for the liquid and its vapor, the other for the solid surface. The resultant surface tension, liquid density and vapor density are found to be well predicted when compared with the experimental data.
