Rising bubble in a cell with a high aspect ratio cross-section filled with a viscous fluid and its connection to viscous fingering
We investigate, both experimentally and theoretically, the velocity and shape of bubbles that rise in a vertical cell with a rectangular cross-section due to buoyancy. The shorter length of the cross-section is comparable to, and the longer length is larger than, the capillary length. This geometry...
