When a drop impacts on a liquid surface it entraps a small amount of air under its centre as
the two liquid surfaces meet. The contact occurs along a ring enclosing a thin disk of air. We …

… Thoroddsen et al. (2005a) used the ISIS high-speed camera to look at the coalescence of air
bubbles in ethanol… drop coalescing with a pool of ethanol. Images show intensity difference …

When two liquid drops come into contact, they coalesce rapidly, owing to the large curvature
and unbalanced surface-tension forces in the neck region. We use an ultra-high-speed …

Two bubbles brought into contact will coalesce rapidly. We study experimentally the initial
coalescence motions in the neck region connecting the two bubbles, using an ultrahigh-speed …

A bubble is slowly grown from a vertical nozzle until it becomes unstable and pinches off.
We use ultra-high-speed video imaging, at frame-rates up to 1 million fps, to study the …

We present experimental observations of the disk of air caught under a drop impacting onto
a solid surface. By imaging the impact through an acrylic plate with an ultra-high-speed …

… We also performed some disruption experiments with ethanol … due to the higher volatility of
ethanol. It is unlikely that plasma … combustion/detonation of ethanol vapor above the droplet …

When a drop impacts at low velocity onto a pool surface, a hemispheric air layer cushions
and can delay direct contact. Herein we use ultra-high-speed video to study the rupture of this …

When two drops of different miscible liquids are brought into contact, their coalescence speed
is governed by the liquid having the weaker surface tension. Marangoni waves propagate …
