Early time kinetics of a system with conserved order parameter quenched into unstable two-phase region of the phase diagram is considered. We study the influence of random inhomogeneities of the order parameter distribution, present already in the system before the quench, on the process of...

A study of a phase separation process in stochastic systems with a field dependent kinetic coefficient and an internal multiplicative noise is presented. Dynamics of spinodal decomposition at early and late stages is investigated by computer simulations where the domain growth law is...

Spinodal decomposition in a three-dimensional Lennard–Jones system with one million particles is studied via molecular dynamics simulations. The interfacial width in the system is about 40 times smaller than the linear system dimension, i.e., the system size therefore is comparable to recent...

Thermally induced coupling of gelation and phase separation in polysaccharide aqueous solutions has a complex feature because of critical and tricritical phenomena, thermally induced hydrophobic interaction, and molecular-weight distribution of the polysaccharide. To elucidate the process, the...

We review our understanding of surface-directed spinodal decomposition (SDSD), i.e., the interplay of wetting and phase separation in an unstable AB mixture placed in contact with a wetting surface. In this context, we present results for two problems, viz., SDSD in a semi-infinite geometry with...

A model for diffusion and phase separation which takes into account exponential relaxation of the solute diffusion flux and its fluctuations is developed. The model describes a system undergoing phase separation governed by a partial differential equation of hyperbolic type. The analysis is done...

We propose a novel method to obtain averaged interface curvature of complex fluids from their scattered intensity without reference to any specific models. The averaged interface curvature of binary mixtures undergoing spinodal decomposition can be obtained with this method. It was found that...

We present comparisons of results on the late stage dynamics of spinodal decomposition (SD) obtained by the computer simulation based on the time-dependent Ginzburg-Landau equation with hydrodynamic interaction and experiments of a polymer mixture of deuterated polybutadiene and polybutadiene....

We present a computer simulation study of spinodal decomposition with one of the two phases freezing in a glassy state during phase separation. As a model we used the Cahn-Hilliard equation with a concentration-dependent mobility coefficient which decreases rapidly with increasing concentration...

A new multiphase lattice Boltzmann model based on the cascaded collision operator is developed to study the spinodal decomposition of critical quenches in the inertial hydrodynamic regime. The proposed lattice Boltzmann model is able to investigate simulations of multiphase spinodal...
