What is it about?

We have studied how a very small bubble moves through a model vortex, called a Lamb-Oseen vortex. This allows us to examine the underlying physics of how bubbles can be trapped in a vortex, how long they are trapped, and other unique features of their trajectories.

Why is it important?

Particle tracking in turbulence is widely applicable, and our goal was to use a simplified model to easily sift through data and determine some important features of bubble entrapment in a vortex, such as residence time of the bubble and trapping potential of a vortex. Our results may be applied to much more complicated flows which involve vortices (such as wall-bounded turbulence) with appropriate scaling.
