Simple model of capillary condensation in porous media

| Sumario: | We employ a simple model to describe the phase behavior of [formula presented] and Ar in a hypothetical porous material consisting of a regular array of infinitely long, solid, parallel cylinders. We find that high porosity geometries exhibit two transitions: from vapor to film and from film to capillary condensed liquid. At low porosity, the film is replaced by a “necking” configuration, and for a range of intermediate porosity there are three transitions: from vapor to film, from film to necking and from necking to a capillary condensed phase. © 2002 The American Physical Society. |
