摘要：

The hydrodynamic effects on the late-stage kinetics in spinodal decomposition of multicomponent fluids are examined using a lattice Boltzmann scheme with stochastic fluctuations in the fluid and at the interface. In two dimensions, the three- and four-component immiscible fluid mixture (with a 1024(2) lattice) behaves like an off-critical binary fluid with an estimated domain growth of t(0.4+/-0.03) rather than t(1/3) as previously estimated, showing the significant influence of hydrodynamics. In three dimensions (with a 256(3) lattice), we estimate the growth as t(0.96+/-0.05) for both critical and off-critical quenches, in agreement with phenomenological theory.
