Hydrodynamic spinodal decomposition: Growth kinetics and scaling functions

We examine the effects of hydrodynamics on the late-stage kinetics in spinodal decomposition. From computer simulations of a lattice Boltzmann scheme we observe, for critical quenches, that single-phase domains grow asymptotically like ${\mathit{t}}^{\mathrm{\alpha }}$, with α≊0.66 in two dimensions and α≊1.0 in three dimensions, both in excellent agreement with theoretical predictions.
