For negligible inertial and buoyancy effects, respectively, small Reynolds (Re) and Bond (Bo) numbers, the thickness of the liquid film depends only on the flow capillary number (Ca).However, buoyancy effects are … hempz whipped marshmallow mint lip balmWebAbstract. The motion and interaction of discrete bubbles in porous materials is studied numerically using a network model. The goal is to extend analytical results for the motion of bubbles through a single straight tube to a more ‘realistic’ geometry for porous materials, modeled here as a planar network of straight tubes of different radii. language for life b2 tests and resources
