Effect of Contact Angle Hysteresis on Evaporation Dynamics of a Sessile Drop on a Heated Surface [PDF]

open access: yesJournal of Applied Fluid Mechanics, 2022
Contact angle hysteresis (CAH) is a significant factor affecting the drop motion on solid substrates. A model of CAH is introduced to explore the influence of CAH on the dynamics of a sessile drop on a uniformly heated surface, and a two-dimensional ...
