We formulate a mean-field (MF) dynamical model for vacancy-mediated phase separation in ternary ABV mixtures, where A and B refer to the separating components; and V to vacancies. We use this model to obtain numerical results for the scaled structure factor and the characteristic length scale, which are then compared with results from a MF dynamical model of phase separation via the usual Kawasaki-exchange mechanism.
