We study the phase separation of water and oil in a water-oil-surfactant mi
croemulsion, from a totally disordered phase in two dimensions by means of
the cell dynamical system (CDS) simulations on the basis of the time-depend
ent Ginzburg-Landau (TDGL) modal with two order parameters. From our result
s of the bicontinuous and droplet patterns, the scaling law and the Pored's
law of the structure factor are observed.
