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

Abstract EN

The asymptotical behavior of order parameter in confined binary mixture is considered in one-dimensional geometry.

The interaction between bulk and surface forces in the mixture is investigated.

Its established conditions are when the bulk spinodal decomposition may be ignored and when the main role in the process of formation of the oscillating asymptotic periodic spatiotemporal structures plays the surface-directed spinodal decomposition which is modelled by nonlinear dynamical boundary conditions.
