Phase separations in films of liquid binary mixtures are studied numerically from the view point of fluid dynamics. The model of this study is the two-phase shallow water equations with driving forces of phase separations based on Ginzburg-Landau model. Numerical experiments are performed to investigate the effects of the volume fraction on phase separations. Phase separations in the early stage are studied by a new equation derived from the two-phase shallow water equations. In the late stage, it is shown that viscous flows play an important role. Differences on phase separations between flows and diffusion processes are discussed.
