Abstract : In this paper we discuss he results of computer simulations of the time-dependent Ginzburg-Landau equation appropriate to the spinodal decomposition of a two-component mixture with a conserved order parameter. The results for quantities of theoretical interest, such as the probability that the concentration has a particular value in a particular cell, as well as experimentally accessible quantities such as the structure function, are presented. For reasons of computer space, the simulation was done in two dimensions. The effects of incompressible flow, which might be important in some experimental situations, were not included in these calculations. (Author)
