I am wondering if there is any equation to predict the evaporation of a sessile droplet. I would like to apply for a mix of two organic solvents.
Thank you in advance.
Dear David Martínez Pérez, cited below are two articles in which this question is addressed. Both papers are available on RG. Also, please find attached another paper as pdf file.
Article Evaporation kinetics of sessile droplets of aqueous suspensi...
Article A New Way of Assessing Droplet Evaporation Independently of ...
Dear all, simple google search lead to an undermined number of publications. I think better will be to focus on one experimental strategy, such as the use of additives or playing on geometry (or topograghy) to study the evaporation kinetics. At the physics department of the Max-Planck Institute of Colloid and Interfaces - Golm, Posdam, Germany, they have many sophisticated lab setup facilities to perform this type of studies. If you are interested, I think Prof. H. Mohwald is the one to contact if he is still active. I have attached two recent documents on this topic. My Regards
Dear David, together with my paper recommended by Frank in the first answer, if you want an analytical equation to predict evaporation of a sessile droplet, here is the link to my paper published on Langmuir in 2018: Article Analytical Model for Diffusive Evaporation of Sessile Drople...
A simpler version of it: Article Theoretical and experimental analysis of droplet evaporation...
Experimentally, if you do some analysis based on the transient shape and volume of evaporating sessile droplets, this paper could provide some useful tips: Article Transient Volume of Evaporating Sessile Droplets: 2/3, 1/1, ...
Hope it helps
