SURFACE-DIRECTED TWO-DIMENSIONAL WAVE STRUCTURES IN CONFINED BINARY MIXTURES
The process of formation of two-wave structures in binary mixtures (for instance, polymer blends or binary alloys), which is described by the Cahn-Hilliard (CH) equation with dynamic boundary conditions with feedback, is considered. Asymptotic periodic impulse structures of relaxation, preturbulent and turbulent type with finite, countable or uncountable number of fronts of discontinuities per a period are studied. It is found that asymptotic structures are elements of the attractor of the initial value boundary problem. Application to a square-shaped binary polymer is considered. Computer simulation describing the formation of crystallites in melts is done.
