Viscosity as a function of the shear rate γ. Steady-state (circles) and D-NEMD (triangles) data of this work are shown along with steady-state results of Ref. 19 (crosses).
D-NEMD transient behavior of T conf for different values of M ζ (indicated in the legend) with γ = 0.50 (a) and γ = 5.0 (b).
Behavior of ηγ(t) for progressively longer simulation runs, t p = 1.0 t.u. (circles), t p = 2.0 t.u. (triangles), and t p = 4.0 t.u. (diamonds), with γ = 0.10 (a) and γ = 5.0 (b). Lines are the best-fits ηγ, FIT(t) obtained for the t p = 1.0 t.u. trajectories. For clarity sake, data points and curves are progressively shifted by 0.2 along the vertical axis.
Behavior of ηγ(t) for a progressively larger non-equilibrium configurations (indicated in the legend), with γ = 0.50 (a) and γ = 5.0 (b). For clarity sake, point data are progressively shifted by 0.2 along the vertical axis.
Behavior of ηγ(t) with (full symbols) and without (open symbols) enforced configurational thermostat, for different shears γ indicated in the legend.
ηγ(t) (full lines) resolved into the configurational (dashed lines) and kinetic (dotted lines, appearing almost superimposed at the bottom) contributions, see Eq. (19) , with γ = 0.50, 1.0, 2.0, and 5.0 (from top to bottom).
Steady-state and D-NEMD data for the viscosity at different shears. Uncertainties are reported in parentheses.
