Hydrodynamic fluctuation theory of spinodal decomposition: The linear regime

Abstract

We present the first hydrodynamic theory of spinodal decomposition in the fluid phase which accounts for stochastic fluctuations in the stress tensor and heat flux and which incorporates a nonlocal driving force through the pressure gradient dependence. Comparison is made with a molecular dynamics computer experiment for a one-component fluid, and good agreement between theory and experiment is demonstrated. © 1982.
