Role of three-body interactions in formation of bulk viscosity in liquid argon
journal contribution
posted on 2013-04-24, 14:51 authored by Sergey V. LishchukWith the aim of locating the origin of discrepancy between experimental and computer simulation
results on bulk viscosity of liquid argon, a molecular dynamic simulation of argon interacting via
ab initio pair potential and triple-dipole three-body potential has been undertaken. Bulk viscosity,
obtained using Green-Kubo formula, is different from the values obtained from modeling argon
using Lennard-Jones potential, the former being closer to the experimental data. The conclusion is
made that many-body inter-atomic interaction plays a significant role in formation of bulk viscosity.
