title: Dissolutive Capillary Penetration with Expanding Pores and Transient Contact Angles.
abstract: The penetration kinetics of a cylindrical capillary and a capillary porous body with a temporally expanding capillary radius due to reactive dissolution ahead of the liquid front is modeled under conditions where the equilibrium contact angle is not attained during at least part of the penetration process. These effects cause deviations from the predictions of the Washburn equation, with the actual penetration kinetics depending upon the rate processes involved. Copyright 2000 Academic Press.
