The long-time behaviour of two-dimensional systems undergoing spinodal decomposition is studied numerically with the aid of a cell-dynamical approach both without and with noise. In both cases, the representative length scale of the pattern behaves as l(t) approximately tphi, where the exponent phi crosses over from approximately 0.28 to approximately 0.33. The crossover time increases with an increase in amplitude of the noise.
