The results show that when a droplet evaporates sufficiently fast it exhibits a vigorous interior flow that is driven by surface tension gradients.Abstract:
Although droplet evaporation is widely assumed to be a diffusion process, our results show that when a droplet evaporates sufficiently fast it exhibits a vigorous interior flow. This flow is driven by surface tension gradients. The typical interior flow field behavior is shown as well as measurements of the droplet surface area and volume as it evaporates. We also discuss the droplet lifetime and how the system tends toward a state of marginal stability. \textcopyright{} 1996 The American Physical Society.read more

Dynamics and stability of thin liquid films
Richard V. Craster,Omar Matar +1 more
TL;DR: The dynamics and stability of thin liquid films have fascinated scientists over many decades: the observations of regular wave patterns in film flows along a windowpane or along guttering, the patterning of dewetting droplets, and the fingering of viscous flows down a slope are all examples that are familiar in daily life.

Evaporation of pure liquid sessile and spherical suspended drops: a review.
TL;DR: This paper presents a review of the published articles for a period of approximately 120 years related to the evaporation of both sessile drops and nearly spherical droplets suspended from thin fibers.

Infrared visualization of thermal motion inside a sessile drop deposited onto a heated surface
TL;DR: In this paper, an infrared camera coupled with a microscopic lens giving a spatial resolution of 10 μm was used to observe the evaporation of sessile drops in infrared wavelengths, including ethanol, methanol and FC-72.

Evaporation of a thin film: diffusion of the vapour and Marangoni instabilities
TL;DR: In this article, the stability of a thin liquid film on a solid substrate is investigated within lubrication theory and the results of the linear stability analysis are compared with the experiments of Poulard et al.
