Gravity-driven migration of bubbles and/or solid particles near a free surface

Abstract : We investigate the challenging problem of bubble(s) and rigid particle(s) interacting near a free surface. The time-dependent bubble(s) and free surface shapes are determined for a large range of Bond number by solving the creeping flow induced by the bubble(s) and the particle(s) motion. This works extends the boundary-integral formulation handled in a recent work solely dealing with bubble(s) ascending toward a free surface.
