Effect of threehyphen;body forces on the shear viscosity of liquid argon

摘要

We present nonequilibrium molecular dynamics simulations of pure argon at a temperature of 135 K and density of 1.034 gm/cc using the highly accurate Barkerndash;Fisherndash;Watts (BFW) model for the intermolecular potential. We consider the BFW potential both with and without the Axilrodndash;Teller threehyphen;body interaction. We find that the threehyphen;body potential has a very small effect on the shear viscosity: The predicted value in the presence of threehyphen;body forces is 3percnt; less than that obtained without threehyphen;body forces.
