Drop impact on a solid surface

C Josserand, ST Thoroddsen - Annual review of fluid mechanics, 2016 - annualreviews.org
A drop hitting a solid surface can deposit, bounce, or splash. Splashing arises from the
breakup of a fine liquid sheet that is ejected radially along the substrate. Bouncing and …

Water penetration through a superhydrophobic mesh during a drop impact

S Ryu, P Sen, Y Nam, C Lee - Physical review letters, 2017 - APS
When a water drop impacts a mesh having submillimeter pores, a part of the drop penetrates
through the mesh if the impact velocity is sufficiently large. Here we show that different …

Droplet fragmentation using a mesh

D Soto, HL Girard, A Le Helloco, T Binder, D Quéré… - Physical review fluids, 2018 - APS
Atomization and spray generation naturally occur around us in a wide variety of situations
ranging from drop impacts to bubble bursting. However, controlling this process is key in …
