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{sup 2} lattice) behaves like an off-critical binary fluid with an estimated domain growth of t{sup 0.4 +/= 0.03} rather than t{sup 1/3} as previously estimated, showing the significant influence of hydrodynamics. In three dimensions (with a 256{sup 3} lattice), we estimate the growth as t{sup 0.96 +/= 0.05} for both critical and off-critical quenches, in agreement with phenomenological theory.
