Ordering processes in porous media

The ordering processes in a binary liquid mixture confined in a Vycor type of pore and at temperatures near the transition temperature of the pure system ${\mathit{T}}_{\mathit{c}}$ are studied using a kinetic Ising model and the method of Monte Carlo simulations. The results for dynamics show quite clear signatures of the pore width but no notable difference between T>${\mathit{T}}_{\mathit{c}}$ and T<${\mathit{T}}_{\mathit{c}}$. In the results for statics, the small angle part of the structure factor increases rapidly as T approaches ${\mathit{T}}_{\mathit{c}}$ in the one-phase region. This suggests the onset of ordering but the fluctuation of energy shows no sign of criticality.
