Abstract

We simulate late-stage coarsening of a three-dimensional symmetric binary fluid. With reduced units l,t (with scales set by viscosity, density, and surface tension) our data extends two decades in t beyond earlier work. Across at least four decades, our own and others' individual datasets (<1 decade each) show viscous hydrodynamic scaling (l similar to a+bt), but b is not constant between runs as this scaling demands. This betrays either the unexpected intrusion of a discretization (or molecular) lengthscale, or an exceptionally slow crossover between viscous and inertial regimes. [S1063-651X(99)51102-1].
