Mechanics of Bubbles in Sludges and Slurries: Modeling Studies of Particulate Materials

PDF Version Also Available for Download.

Description

(1) Model effective compressibility of bubbles dispersed in a rigid porous medium. Account for capillary forces on bubbles that restrain bubble response to ambient pressure changes, and therefore affect compressibility of bubbles. Account for diffusive growth process in context of strong capillary forces, that may bias distribution of bubble sizes in population and thereby affect effective compressibility. (2) Model yield stress and effective compressibility of a dispersion of gas, solids and liquid (assumed here to be deformable), focusing on capillary interactions between solid and bubbles, and effects of these interactions on mechanical properties.
