Modeling the Evaporation of Drying Sessile Droplets with Buoyancy Driven Internal Convection

Droplet evaporation is a fundamental phenomenon encountered in diverse applications such as inkjet printing, DNA mapping, film coating, and electronics cooling. Modeling the evaporation process of a sessile droplet is complicated because of the coupling of several physical phenomena occurring in dif...
