Molecular dynamics study of two-and three-dimensional classical fluids using double Yukawa potential

Abstract

We have carried out a molecular dynamics simulation of two- and three- dimensional double Yukawa ∞uids near the triple point. We have compared some of the static and dynamic correlation functions with those of Lennard{Jones, when parameters occurring in double Yukawa potential are chosen to flt Lennard{Jones potential. The re- sults are in good agreement. However, when repulsive and attractive parameters occurring in double Yukawa potential are varied, we found distinct difierences in static and dynamic correlation functions. We have also compared the two-dimensional correlation functions with those of three-dimensional to study the efiect of dimensionality, near the triple point region.
