Interlayer water in clays plays an important role in soil swelling
and frost heaving processes. In order to understand the interaction
between water and clay surfaces, the influence of the surfaces on
fluid was investigated. Average equilibrium properties of argon
fluid between two parallel argon walls of simple cubic lattice were
computed at various wall separation and temperature by means of the
molecular dynamic (MD) method. It was confirmed from local density
profiles and pair correlation function that long-range order was
formed in the fluid confined between the walls. With increasing the
wall separation, average pressure of the fluid increased at the
temperature over 100 K, at which freezing point of the fluid might
depress in terms of the interaction between the fluid and the wall
atoms.
