Abstract

In bubbly turbulent flows, the deformation of the bubble is known to play an important role in the interaction between the carrier phase and the dispersed phase. In the present paper, we experimentally study an idealized version of the problem where we look at the interaction of a deforming air bubble (nonzero Weber number) and a rigid buoyant particle (zero Weber number) with a single vortex ring (in water) for a large range of ring-circulation-based Reynolds numbers (Re=Γ/
