Abstract
The vortex structure created by a bursting bubble has been photographically studied. A vortex model has been constructed, which describes the evolution of the structure, and the phenomenon has been simulated numerically using two two-dimensional vortex blob models. The bubble is situated on a shallow pool of fluid that is on the top face of a vertical cylinder. Two upward-moving vortex rings with colinear axes are formed within 15 ms after bubble rupture. The two rings leapfrog to form a structure consisting of a vortex ring that sheds lobes of fluid that are sometimes similar in appearance to hairpin vortex loops. This evolution occurs within 100 ms of the initiation of bubble rupture, when the ring Reynolds number is approximately 170. The computational model produced images with a close resemblance to the physical structure, and was used to support the theory that the trailing lobes are rotational and consist of the vortex ring that was initially leading.
