Structure effects and phase equilibria of Lennard-Jones mixtures in a cylindrical pore.

The effect of fluid confinement in a narrow cylindrical pore is studied by means of a density-functional approach. An extension of the smoothed-density approximation to the two-component case is employed to explore the structure and phase behaviour of a mixture in a cylindrical pore. Contact is made with the previous local-density treatment and with the macroscopic thermodynamic approach.
