The nature of bubble entrapment in a Lamb–Oseen vortex

Bubble trajectories in the presence of a decaying Lamb–Oseen vortex are calculated using modified Maxey–Riley equation. Some bubbles shown to get trapped within quasi-equilibrium states. All exit at time that is only function Galilei number and Reynolds number. The set initial bubble locations lead entrapment numerically determined show capturing potential single vortex. results provide insight into likelihood vortical structures turbulent flows.
