We consider the time evolution of a sessile drop of volatile partially wetting liquid on a rigid solid substrate. Thereby, the drop evaporates under strong confinement, namely, it sits on one of the two parallel plates that form a narrow gap. First, we develop an efficient mesoscopic thin-film description in gradient dynamics form. It couples the diffusive dynamics of the vertically averaged vapour density in the narrow gap to an evolution equation for the profile of the volatile drop. The underlying…

Numerical simulation of dip-coating in the evaporative regime

TLDR
A hydrodynamic model is used for numerical simulations of a polymer solution in a dip-coating-like experiment where the liquid flow is driven by evaporation, in contrast to the well-known Landau-Levich regime dominated by viscous forces.

Asymptotic analysis of the evaporation dynamics of partially wetting droplets

We consider the dynamics of an axisymmetric, partially wetting droplet of a one-component volatile liquid. The droplet is supported on a smooth superheated substrate and evaporates into a pure vapour

On evaporation of sessile drops with moving contact lines

We consider theoretically, computationally and experimentally spontaneous evaporation of water and isopropanol drops on smooth silicon wafers. In contrast to a number of previous works, the solid

Morphology changes in the evolution of liquid two-layer films.

TLDR
It is shown that the initial instability can be of a varicose, zigzag, or mixed type and in the nonlinear stage of the evolution the mode type can change via switching between two different branches of stationary solutions or via coarsening along a single branch.

Nonlocal description of evaporating drops

We present a theoretical study of the evolution of a drop of pure liquid on a solid substrate, which it wets completely. In a situation where evaporation is significant, the drop does not spread, but

Evaporation of a thin film: diffusion of the vapour and Marangoni instabilities

The stability of an evaporating thin liquid film on a solid substrate is investigated within lubrication theory. The heat flux due to evaporation induces thermal gradients; the generated Marangoni

Macroscopic Model for Sessile Droplet Evaporation on a Flat Surface

TLDR
This work proposes a simple model hinged on a surface free-energy-based relaxation dynamics of the droplet shape, a diffusive evaporation model, and a contact line pinning mechanism governed by a yield stress that reproduces the known dynamics of droplets shape relaxation and of dropletEvaporation, both in the absence and in the presence of contact linePinning.

TLDR
It is illustrated that the underlying solution structure might be very complex but can be better understood when comparing the much simpler results for the dewetting liquid film, and that the numerical continuation techniques employed can shed some light on this structure in a more convenient way than time-stepping methods.

Gradient-dynamics model for liquid drops on elastic substrates.

TLDR
A reduced long-wave model is proposed that captures the main qualitative features of statics and dynamics of soft wetting, but which can be applied to ensembles of droplets and it is shown that the dominant coarsening mode changes with substrate softness in a nontrivial way.
