Coalescence induced domain growth near a wall during spinodal decomposition

Intermittent dynamics and logarithmic domain growth during the spinodal decomposition of a glass-forming liquid.

We use large-scale molecular dynamics simulations of a simple glass-forming system to investigate how its liquid-gas phase separation kinetics depends on temperature. A shallow quench leads to a fully demixed liquid-gas system whereas a deep quench makes the dense phase undergo a glass transition and become an amorphous solid. This glass has a gel-like bicontinuous structure that evolves very s...

Evolution of speckle during spinodal decomposition.

Time-dependent properties of the speckled intensity patterns created by scattering coherent radiation from materials undergoing spinodal decomposition are investigated by numerical integration of the Cahn-Hilliard-Cook equation. For binary systems which obey a local conservation law, the characteristic domain size is known to grow in time tau as R=[Btau](n) with n=1/3, where B is a constant. Th...

Domain formation and growth in spinodal decomposition of a binary fluid by molecular dynamics simulations.

The two initial stages of spinodal decomposition of a symmetric binary Lennard-Jones fluid have been simulated by molecular dynamics simulations, using a hydrodynamics-conserving thermostat. By analyzing the growth of the average domain size R(t) with time, a satisfactory agreement is found with the R(t) proportional t1/3 Lifshitz-Slyozov growth law for the early diffusion-driven stage of domai...

Spinodal decomposition in microemulsions

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...
