Droplet impact on surfactant-laden thin liquid films: Vortex ring dynamics
Hatim Ennayar, Hyoungsoo Kim, Jeanette Hussong
Droplet impact on surfactant-laden thin liquid films is investigated experimentally with emphasis on vortex ring dynamics. Bottom- and side-view imaging reveal that increasing surf…

On the vortex ring formation and mixing in thin films upon droplet impact
Hatim Ennayar, Juan Camilo Dueñas Torres, Juan Camilo Dueñas Torres +3
When a droplet impacts a liquid film, a vortex ring form and govern momentum and species transport. We experimentally investigate vortex ring formation, propagation and instability…
