Metastable states in liquid–gas phase transition. Simulation by the method of molecular dynamics

The method of molecular dynamics is used to investigate the $p$, $\rho$, $T$-properties and the structural characteristics of the Lennard–Jones fluid in the stable and metastable states in the liquid–gas phase transition. The calculation results demonstrate the presence of phase separation in molecular models at close-to-spinodal supersaturation. The effect of the cut-off radius of the interparticle potential on the process of phase transformation is analyzed, and the position of spinodal of superheated liquid and supersaturated vapor is estimated.
