Chapter 2: Wetting and Contact Line Motion
Published:01 Jun 2022
Key aspects of wetting phenomena and their coupling to evaporation and fluid flow near contact lines are reviewed in the context of sessile droplets of both Newtonian and complex fluids including suspensions, polymers, surfactant/polymer solutions, polymer–colloid mixtures, and biological fluids. The role of sessile droplet models in understanding transmission of infectious diseases by respiratory droplets is elucidated. Both mathematical modeling approaches and experimental techniques are discussed.
