Evaporation of sessile drops under combined diffusion and natural convection
TLDR
In this article, the authors investigated the range of applicability of a commonly used assumption for evaporation models of sessile drops, that the transport mechanism that controls the eva-oration is vapor diffusion.About:

Transport and deposition patterns in drying sessile droplets
TL;DR: The literature on drying sessile droplets and deposition of suspended material is reviewed including the simple explanation of the “coffee ring” deposit given by Deegan et al. as discussed by the authors.

Recent advances in droplet wetting and evaporation
TL;DR: This review presents the physics involved during droplet wetting and evaporation by focusing on the evporation dynamics, the flow motion, the vapour behaviour, the surface tension, and the wetting properties.

TL;DR: In this paper, the evaporation rate from single drops as well as collections of drops on a solid substrate, both experimentally and theoretically, is studied. But the authors focus on the single drop and do not consider the effect of diffusion of water through the air.

TL;DR: In this paper, the influence of the surface properties of substrates on the evaporation process is investigated, and it is shown that the dynamics of the evaporative rate are proportional to the dynamic of the wetting radius.

Capillary flow as the cause of ring stains from dried liquid drops
TL;DR: In this article, the authors ascribe the characteristic pattern of the deposition to a form of capillary flow in which pinning of the contact line of the drying drop ensures that liquid evaporating from the edge is replenished by liquid from the interior.
Journal ArticleDOI
Contact line deposits in an evaporating drop
TL;DR: A theory is described that predicts the flow velocity, the rate of growth of the ring, and the distribution of solute within the drop that is driven by the loss of solvent by evaporation and the geometrical constraint that the drop maintain an equilibrium droplet shape with a fixed boundary.

Evaporation of a Sessile Droplet on a Substrate

TL;DR: In this article, the evaporation of a sessile droplet with a pinned contact line was investigated experimentally, by analytic theory and by computation using the finite element method (FEM).
Journal ArticleDOI
Pattern formation in drying drops
TL;DR: The drop itself can generate one of the essential conditions for ring formation to occur: contact line pinning, and it is shown that when self-induced pinning is the only source of pinning an array of patterns-that include cellular and lamellar structures, sawtooth patterns, and Sierpinski gaskets-arises from the competition between dewetting and contact linePinning.
