Direct imaging of polymer filaments pulled from rebounding drops
Ziqiang Yang, Peng Zhang, Meng Shi +4
Polymer filaments form the foundation of biology from cell scaffolding to DNA. Their study and fabrication play an important role in a wide range of processes from tissue engineeri…
Multitude of singular jets during the collapse of drop-impact craters
Zi Qiang Yang, Yuan Si Tian, Sigurður T. Thoroddsen
We study singular jets from the collapse of drop-impact craters, when the drop and pool are of different immiscible liquids. These jets emerge from a dimple at the bottom of the re…
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…
How to freeze drops with powder
Jeremy Marston, Ying Zhu, Ivan Vakarelski +1
This document accompanies fluid dyanmics video entry V83911 for APS DFD 2012 meeting. In this video, we present experiments on how drop oscillations can be "frozen" using hydrophob…
