Abstract: The motion of a tiny bubble (< 1mm) in a neighborhood of a solid sphere falling through a liquid is studied. A model assuming irrotational flow around the sphere and spherical bubble shape is provided; this model is validated by comparison with the experiment. The model can be further simplified by neglecting inertial forces, which are negligible in present experiments. Results of the model are provided also for the opposite limit, in which the inertial forces are dominating the bubble motion.
