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 [ital t][sup [alpha]], with [alpha][approx]0.66 in two dimensions and [alpha][approx]1.0 in three dimensions, both in excellent agreement with theoretical predictions.
