Abstract: The encounter effect on the dynamics of fluctuations in phase separations of off-critically quenched binary systems is studied by performing three-dimensional computer simulations of the droplet growth model proposed recently by the authors. The dynamical behavior of the scattering structure function, including the dynamical scaling, the temporal power laws, and the crossovers have been investigated. At higher volume fractions, the encounter effect is shown to strongly influence not only the dynamics of the single-droplet-size distribution function, leading to flattening and broadening of the distribution function, but also the dynamics of fluctuations in phase- separating systems, leading to sharpening and narrowing the structure function.
