Abstract
We examine the dynamic and thermodynamic properties of adsorbed liquid films in cylindrical cavities. We find a dynamical stability limit for the thickness of films adsorbed uniformly on the walls. This limit is shown to coincide with a thermodynamic stability limit which depends on both substrate and capillary forces. The Kelvin equation describing capillary condensation is generalized to include the substrate interaction. The low-temperature properties of the films are calculated.Keywords
