Abstract The evaporation of sessile drops in quiescent air is usually governed by vapour diffusion. For contact angles below $9{0}^{\ensuremath{\circ} } $ , the evaporative flux from the droplet tends to diverge in the vicinity of the contact line. Therefore, the description of the flow inside an evaporating drop has remained a challenge. Here, we focus on the asymptotic behaviour near the pinned contact line, by analytically solving the Stokes equations in a wedge geometry of arbitrary contact… Expand
Stokes flow in a drop evaporating from a liquid subphase
The evaporation of a drop from a liquid subphase is investigated. The two liquids are immiscible, and the contact angles between them are given by the Neumann construction. The evaporation of theExpand
Modelling the contact-line dynamics of an evaporating drop
We study the evolution of a thin, axisymmetric, partially wetting drop as it evaporates. The effects of viscous dissipation, capillarity, slip, gravity, surface-tension gradients, and contact-angleExpand
A model for pattern deposition from an evaporating solution subject to contact angle hysteresis and finite solubility.
This model takes into account the three-phase contact angle hysteresis and the deposition of the solute whenever its concentration exceeds the solubility limit, and replaces an exact geometric description of the vicinity of the contact line with general insights about the concentration and its flux.

A Mathematical Model of Fluid Flow in Evaporating Droplets Using Wedge Geometry
As a droplet of liquid evaporates, particles within the droplet are often pulled to the edge and deposited in a ring-shaped pattern. This is known as the coffee-ring effect. The coffee-ring effect isExpand

Buoyancy-driven convection of droplets on hot nonwetting surfaces.
The global linear stability of a water drop on hot nonwetting surfaces is studied and it is suggested that the experimental observation for a droplet with β=110^{∘} corresponds to the steady toroidal base flow, while for β=160^{ ∘}, the m=1 instability promotes the rigid body rotation motion.

Evaporation at microscopic scale and at high heat flux

Generalized formulation for evaporation rate and flow pattern prediction inside an evaporating pinned sessile drop
Abstract When a sessile drop is heated from below, it evaporates and it induces a cooling effect in a zone close to the drop surface. The important evaporation rate at the contact line, the surfaceExpand

The problem of Stokes flow inside a two-dimensional droplet, representing the cross section of an evaporating liquid line lying on a flat surface, is considered, leading to the biharmonic equation in bipolar coordinates that can be used with any type of evaporation mechanism, including diffusion, convection, or kinetically controlled modes.

The leading edge of evaporating droplets.
A systematic study of the drops dynamics is presented, as a basis for forthcoming theoretical work on polydimethylsiloxane oligomers, which are similar to alkanes as far as evaporation rate is concerned, but have lower surface tensions, and therefore smaller dynamic contact angles. Expand
