The Spatiotemporal Oscillations of Order Parameter for Isothermal Model of the Surface-Directed Spinodal Decomposition in Bounded Binary Mixtures

Figure 2

Phase diagram is obtained for the problem with nonlinear boundary conditions, which cause the surface-directed spinodal decomposition, by the theoretical method. Here (a) is the region of unique stable phase; (b) is the region of the spinodal decomposition; (c) is the region of the lamellar phase; (d) is the region of stochastic distributions of the order parameter.
