OS1-2-8 A Study on the Density Fluctuation in Diatomic Fluid around the Critical Point Using Molecular Dynamics Method

Abstract

In this study, we performed the Molecular Dynamics (MD) simulation for the extraction of the density fluctuations around the critical points of 2-Center-Lennard-Jones (2CLJ) fluids, which depend on the internulear distance. As a result, it was confirmed that the density fluctuation forms a ridge as the local maximum value near the critical density, and this tendency was consistent with the experiment by the small-angle X-ray scattering (SAXS).
