Relaxation of a dewetting contact line. Part 1. A full-scale hydrodynamic calculation
The relaxation of a dewetting contact line is investigated theoretically in the so-called ‘Landau–Levich’ geometry in which a vertical solid plate is withdrawn from a bath of partially wetting…
Order-to-disorder transition in ring-shaped colloidal stains.
These experiments with monodisperse colloidal particles reveal a structural transition in the stain, from ordered crystals to disordered packings, and it is shown that this sharp transition originates from a temporal singularity of the flow velocity inside the evaporating droplet at the end of its life.

Previously unexplored length and time scales are accessed and a detailed picture is provided on how the initial contact between the liquid drop and the solid is established, which unambiguously point toward a spreading regime that is independent of wettability.
Breakup of diminutive Rayleigh jets
Discharging a liquid from a nozzle at sufficient large velocity leads to a continuous jet that due to capillary forces breaks up into droplets. Here we investigate the formation of microdroplets from…
Avoided critical behavior in dynamically forced wetting.
This Letter demonstrates experimentally and theoretically that the dynamical wetting transition at which a liquid film gets deposited by withdrawing a vertical plate out of a liquid reservoir is due to the formation of a solitary wave well below the critical point.
Free-surface flows with large slopes: Beyond lubrication theory
- J. Snoeijer
- 1 February 2006
The description of free-surface flows can often be simplified to thin-film (or lubrication) equations, when the slopes of the liquid-gas interface are small. Here, we present a long-wavelength theory…
Theory of the collapsing axisymmetric cavity.
The collapse of an axisymmetric cavity or bubble inside a fluid of small viscosity, like water, is investigated and the local scaling exponent alpha very slowly approaches a universal value according to alpha=1/2+1/[4 square root [-ln(t')]].
Why is surface tension a force parallel to the interface
A paperclip can float on water. Drops of mercury do not spread on a surface. These capillary phenomena are macroscopic manifestations of molecular interactions and can be explained in terms of…

The phase diagram for the existence of stationary film solutions as well as the film profiles are calculated and find excellent agreement with experiment.

It is found that the cone angle is independent of substrate temperature and wetting angle, suggesting a universal, self-similar mechanism that does not depend on the rate of solidification.
