Common vortical wake flows as generated by aircraft, submarines, and flying and swimming animals are dominated by elongated vortical structures. The evolution of these vortices has important consequences for the overall wake dynamics, which affects sound generation, ambient mixing, and the behavior of trailing bodies. Given the high Reynolds number of these vortices, they are susceptible to instabilities arising from small perturbations. In this work, we study a particular form of perturbation on vortex tubes, the core-size perturbation, which leads to a phenomenon known as bursting.
