摘要
We present results from a numerical study of surface-directed spinodal decomposition in a binary fluid mixture, for critical and various off-critical concentrations. We explicitly add a long-range surface interaction term to the bulk free-energy functional leading to preferential attraction of one of the components of the fluid mixture to a solid surface. We also consider hydrodynamic interactions in these model calculations. Results of the wetting layer thickness and the domain size as a function of time and the scaling behavior of the density profile perpendicular to the surface are presented in the fluid inertia controlled regime.
