Abstract Drop coalescence occurs through the rapid growth of a liquid bridge that connects the two drops. At early times after contact, the bridge dynamics is typically self-similar, with details depending on the geometry and viscosity of the liquid. In this paper we analyse the coalescence of two-dimensional viscous drops that float on a quiescent deep pool; such drops are called liquid lenses. The analysis is based on the thin-sheet equations, which were recently shown to accurately capture… 


Influence of droplet geometry on the coalescence of low viscosity drops.
A geometric model is presented that quantitatively captures the transition from 2/3 to 1/2 exponent, and unifies the inertial coalescence of sessile drops and freely suspended drops.
Symmetric and asymmetric coalescence of drops on a substrate.
It is shown that the universal shape of the bridge is accurately described by similarity solutions of the one-dimensional lubrication equation, and predicts that, once the drops are connected on a microscopic scale, the bridge grows linearly in time with a strong dependence on the contact angles.
Coalescence of liquid drops
When two drops of radius R touch, surface tension drives an initially singular motion which joins them into a bigger drop with smaller surface area. This motion is always viscously dominated at early
The initial coalescence of miscible drops
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 along the drop
Coalescence of spreading droplets on a wettable substrate.
The coalescence dynamics of two spreading droplets on a highly wettable substrate is investigated and the scaling behavior is demonstrated to be consistent with a model in which the growth of the meniscus bridge is governed by the viscously hindered flux from the droplets.
Inviscid coalescence of drops
We study the coalescence of two drops of an ideal fluid driven by surface tension. The velocity of approach is taken to be zero and the dynamical effect of the outer fluid (usually air) is neglected.
Viscous to inertial crossover in liquid drop coalescence.
It is argued that the late crossover, not accounted for in the theory, can be explained by an appropriate choice of length scales present in the flow geometry.
Dynamic drying in the early-stage coalescence of droplets sitting on a plate
The early-stage coalescence of two sessile drops is investigated theoretically and experimentally. The coalescence of small sessile drops of diethylene glycol on silicon wafer is induced either by
Hydrodynamics of droplet coalescence.
This work studies droplet coalescence in a molecular system with a variable viscosity and a colloid-polymer mixture with an ultralow surface tension and shows that decreasing the surface tension by a factor of 10(5) opens the way to a more complete understanding of the hydrodynamics involved.
Role of dimensionality and axisymmetry in fluid pinch-off and coalescence.
Pinch-offs in quasi-2D lenses is distinctly different from pinch-off in axisymmetric 3D drops and involves a cascade of satellite droplets which extends to micron length scales, and coalescence is predicted to involve entrainment of the exterior fluid as the droplets merge.
