"Simple Model of Capillary Condensation in Cylindrical Pores"
L. Szybisz and I. Urrutia
Phys. Rev. E 66(5) (2002) 051201/1-11
A simple model based on an approximation of the droplet-like 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: D* (the reduced asymptotic strength of the fluid-adsorber interaction, a function of temperature) and R*(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.
