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

Figure 1

Asymptotically periodic distributions of the order parameter of the relaxation type. The map Φ∶𝑔↦𝑔²+𝜇. Here, 𝛽₁ and 𝛽₃ are stable ordered phases, and 𝛽₂ is unstable disordered phase. If the amplitude of initial bubbles is greater than 𝛽₂, then there are the oscillations. If the amplitude of initial bubbles is less than 𝛽₂, then asymptotic distributions of order parameter tend to the constant value 𝛽₁ [4].
