Ripening Kinetics and Equilibrium States of Bubble Populations in Porous Media
Abstract
A population of bubbles trapped inside a porous medium are in disequilibrium at early times, because each bubble has a different capillary pressure (Pc) (Garing et al., AWR, 2017). At later times, bubbles dissolve into the surrounding fluid and collectively approach a uniform Pc, a phenomenon known as "anti-coarsening Ostwald ripening" (Xu et al., PRL, 2017). Despite valuable insights gained from recent micromodel experiments and pore-network simulations, there is still a lack of a firm theory that describes the statistical evolution dynamics of trapped bubble populations. The goal of this work is to address this knowledge gap.
