Vortex ring induced large bubble entrainment during drop impact
Marie-Jean Thoraval, Yangfan Li, Sigurdur T. Thoroddsen
For a limited set of impact conditions, a drop impacting onto a pool can entrap an air bubble as large as its own size. The subsequent rise and rupture of this large bubble plays a…
Drop impact entrapment of bubble rings
M. -J. Thoraval, K. Takehara, T. G. Etoh +1
We use ultra-high-speed video imaging to look at the initial contact of a drop impacting onto a liquid layer. We observe experimentally the vortex street and the bubble-ring entrap…
Bubble Chandeliers
Sigurdur T. Thoroddsen, Marie-Jean Thoraval, Kohsei Takehara +1
When a drop impacts at very low velocity onto a pool surface it is cushioned by a thin layer of air, which can be stretched into a hemispheric shape. We use ultra-high-speed video…
Bubble Rings Entrapment
Marie-Jean Thoraval, Sigurdur T. Thoroddsen, Kohsei Takehara +1
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…
Von Kármán Vortex Street within an Impacting Drop
Marie-Jean Thoraval, Kohsei Takehara, Takeharu Goji Etoh +5
The splashing of a drop impacting onto a liquid pool produces a range of different sized micro-droplets. At high impact velocities, the most significant source of these droplets is…
