Phase Separation in Two-Dimensional Fluid Mixtures

The phase separation of two-dimensional fluid mixtures was investigated with molecular dynamics simulations. The behavior of both single-component and binary mixtures as a function of temperature, volume fraction, and average fluid density was considered. In both systems, the diffusive coalescence of clusters is the primary mechanism of growth. In binary systems, the shape transformations of merging droplets induce important long-range flow in the system.
