Evaporation of sessile droplets is associated with simple phenomena such as the ring-like spot left by a drying coffee droplet. Evaporation rate plays an important role on the convective motion inside the droplet. These fluxes are for example one of the factors responsible for amyloid fibrillation ...
The paper examines various methods used to study droplet evaporation, including optical microscopy, interferometry, and microfluidics. Recent studies have focused on drop impact, droplet impingement, crystallization, Marangoni flow, and the influence of nanoparticles on the evaporation process of stationary ...
We theoretically examine the drying of a stationary liquid droplet on an inclined surface. Both analytical and numerical approaches are considered, while assuming that the evaporation results from the purely diffusive transport of liquid vapor and that the contact line is a pinned circle. For the ...
Motivated by the space project EFILE, a 2D axisymmetric numerical model in the framework of ALE method is developed to investigate the coupled physical mechanism during the evaporation of a pinned drop that partially wets on a heated substrate. The model accounts for mass transport in surrounding ...
Controlling the dynamics of droplet evaporation is critical to numerous fundamental and industrial applications. The three main modes of evaporation so far reported on smooth surfaces are the constant contact radius (CCR), constant contact angle (CCA), and mixed mode. Previously reported methods for ...

This experimental study investigates the effect of nanoparticles mass fraction as well as the variation of nanoparticles sizes on the viscosity and evaporation ...
The simplest possible experiment is the drying of a droplet on a solid substrate. This phenomenon has been studied macroscopically [7], [8], and evaporation was found to be diverging at the contact line, providing an explanation for the famous “coffee stain”: as well-known, extremely high...
Nanofluid droplet evaporation has gained much audience nowadays due to its wide applications in painting, coating, surface patterning, particle deposition, etc. This paper reviews the drying progress and deposition formation from the evaporative sessile droplets with the suspended insoluble solutes, especial...
Evaporation of a sessile water droplet subjected to forced convection in humid environmentThe influence of air humidity on drying is investigated at four inlet air dew points; Tdp = 273, 292, 313, and 333 K. A numerical model taking into account capillary transport of liquid and internal ...
Experimental evidence of the atmospheric convective transport contribution to sessile droplet evaporation We investigate the contribution of the natural convective transport in the vapor phase on the evaporation rate of an evaporating sessile droplet.
