Growth and scaling in anisotropic spinodal decomposition

Growth and Scaling in Anisotropic Spinodal De- Composition

– We studied phase separation in a particle interacting system under a large drive along x. We here identify the basic growth mechanisms, and demonstrate time self-similarity, finite-size scaling, as well as other interesting features of both the structure factor and the scaling function. We also show that, at late t in two dimensions, there is a unique t−dependent length increasing ly (t) ∼ t ...

Hydrodynamic spinodal decomposition: Growth kinetics and scaling functions.

We examine the effects of hydrodynamics on the late stage kinetics in spinodal decomposition. From computer simulations of a lattice Boltzmann scheme we observe, for critical quenches, that single phase domains grow asymptotically like t, with α ≈ .66 in two dimensions and α ≈ 1.0 in three dimensions, both in excellent agreement with theoretical predictions.

Programs for the calculation of the spinodal decomposition growth rate and the spinodal gap in nanoparticles

This data article contains the programs for the calculation of the spinodal decomposition growth rate and for the modeling of the spinodal gap and concentration profiles in nanoparticles which were used in our article (Pogorelov et al., 2017) [1]. The modeling is based on the mathematical model of spinodal phase decomposition with intercalation rate conditions on the boundaries (Singh et al., 2...

Parallel Spinodal Decomposition

Spinodal decomposition encompasses the ordering dynamics of thermodynamically unstable phases. An example of spinodal decomposition is the separation of the metals in a binary alloy. Because physicists have been unable to develop a fully coherent, consistent , and calculable theory on spinodal decomposition, computational studies have served as valuable sources of information. However, since th...
