Gravity-driven migration of one bubble near a free surface: surface tension effects

Abstract : We pay attention not only to the time dependent film thickness of the liquid film (so-called drainage) between a bubble and a free surface but also to the bubble and free surface shapes when allowing different uniform surface tensions on these surfaces. This is achieved by extending the recent boundary approach recently employed in [1] for surfaces having identical surface tension. Preliminary numerical results clearly show the sensitivity of the drainage and time-dependent surfaces to the surface tension ratio of 3.
