Phase-separation fronts in binary mixtures: simulations and analytical solutions

Abstract: I present a simple model for Phase-Separation fronts induced by a sharp controlparameter front (e.g. an abrupt jump in the temperature). We examined the morphologies formed in the wake of such a front which moves with some prescribed velocity. When this velocity is a constant in time we find very regular, non-equilibrium structures which are oriented either parallel or orthogonal to the imposed front. The main parameters for the morphology formation are volume fraction and front speed. I will present some analytical predictions on the form and size of these structures and validated these predictions with simulations.

The seminar takes place on Monday, December 6, 4:30 p.m. in the ICAMS seminar room UHW 11/1102, Stiepeler Straße 129, 44801 Bochum.
