VOLUME-FRACTION DEPENDENCE OF SCALING FUNCTIONS IN PHASE-SEPARATION PROCESSES OF BINARY-MIXTURES

We present results of a numerical study of the Cahn-Hilliard model of phase separation for a binary mixture quenched deep in the nucleation regime. We study the volume-fraction dependence of the scaling functions for the pair correlation function and the structure factor. Our results indicate that for small volume fraction-phi the shape of the scaling functions depends strongly on phi, whereas for larger volume fractions the scaling functions seem to be independent of phi.
