Spinodal decomposition in fluids: diffusive, viscous and inertial regimes

TL;DR

This paper investigates the process of spinodal decomposition in fluids across diffusive, viscous, and inertial regimes using a Langevin model, with numerical results supporting previous theoretical predictions.

Contribution

It introduces a Langevin-based framework to analyze domain growth in different regimes of fluid spinodal decomposition, confirming earlier scaling theories.

Findings

Numerical results support theoretical scaling predictions

Domain growth behavior varies across regimes

Langevin model effectively captures decomposition dynamics

Abstract

Using a Langevin description of spinodal decomposition in fluids, we examine domain growth in the diffusive, viscous and inertial regimes. In the framework of this model, numerical results corroborate earlier theoretical predictions based on scaling arguments and dimensional analysis.
