Contribution
It presents new visual evidence and analysis of micro-bubble ring entrapment during droplet impact, a phenomenon not extensively documented before.
Findings
Micro-bubble rings are entrapped under impacting drops.
Visual evidence of bubble ring formation during impact.
Insights into fluid dynamics of droplet impact phenomena.
Abstract
We show how micro-bubble rings are entrapped under a drop impacting onto a pool surface. This fluid dynamics video is submitted to the APS DFD Gallery of Fluid Motion 2012, part of the 65th Annual Meeting of the American Physical Society's Division of Fluid Dynamics (18-20 November, San Diego, CA, USA).
