Descripción:

A simple model based on an approximation of the dropletlike model is formulated for studying adsorption of fluids into cylindrical pores. This model yields a nearly universal description of capillary condensation transitions for noble gases confined by alkali metals. The system’s thermodynamical behavior is predicted from the values of two dimensionless parameters: [formula presented] (the reduced asymptotic strength of the fluid-adsorber interaction, a function of temperature) and [formula presented] (the reduced radius of the pore). The phenomenon of hysteresis inherently related to capillary condensation is discussed. The connection to a previously proposed universality for cylindrical pores is also established. © 2002 The American Physical Society.
