Illustrations of the 2-D phase field simulation. (a) Initial concentration field (t = 0, \({S}_{v}^{-1}=47.2\)) containing 5% volume fraction of large particles and 16% of small particles. (b) Final concentration field (t = 7.2 × 105, \({S}_{v}^{-1}=101.5\)). (c) Evolution of characteristic length \({S}_{v}^{-1}\) vs. time t plotted alongside a fit to the expected coarsening power law. (d) Interfacial radius-of-curvature distribution weighted by interfacial length at the times indicated in (c). Two peaks are present corresponding to the small and large particle distributions introduced in the initial condition.
