G. Marcelli et al., The strain rate dependence of shear viscosity, pressure and energy from two-body and three-body interactions, FLU PH EQUI, 183, 2001, pp. 371-379
Non-equilibrium molecular dynamics simulations (NEMD) are reported for the
shear viscosity of xenon using accurate two- and three-body potentials, The
hydrostatic pressure and energy are observed to vary proportionally with t
he square of the strain rate. This is in contrast to the non-analytic three
-halves power dependence on strain rate predicted by mode-coupling theory.
This result is attributed solely to the two-body potential. The main effect
of the three-body potential is to alter the magnitude of the pressure, ene
rgy and viscosity profiles. (C) 2001 Elsevier Science B.V. All rights reser
