On the interaction of a bubble and a vortex ring at high Reynolds numbers

The interaction of a bubble and a vortex ring at high Reynolds numbers could be considered a simplified model of the interaction of a bubble and a turbulent structure of similar size, with the possible subsequent bubble breakup. In this paper, some results from axisymmetric and 3D simulations of the interaction of a bubble and a vortex ring at high Reynolds numbers are presented for different values of the Weber number and vortex ring sizes. Some bubble breakup patterns that could not be obtained by previous axisymmetric boundary integral models are shown. Results obtained are discussed into the framework of the classical Kolgomorov-Hinze theory on bubble breakup and some recent experimental investigations.
