The role of drop shape in impact and splash
Qingzhe Liu, Jack Hau Yung Lo, Ye Li +3
The impact and splash of liquid drops on solid substrates are ubiquitous in many important fields. However, previous studies have mainly focused on spherical drops while the non-sp…
Mechanism of Contact between a Droplet and an Atomically Smooth Substrate
Hau Yung Lo, Yuan Liu, Lei Xu
When a droplet gently lands on an atomically smooth substrate, it will most likely contact the underlying surface in about 0.1 s. However, theoretical estimation from fluid mechani…
Kelvin Helmholtz instability in an ultrathin air film causes drop splashing on smooth surfaces
Yuan Liu, Peng Tan, Lei Xu
When a fast-moving drop impacts onto a smooth substrate, splashing will be produced at the edge of the expanding liquid sheet. This ubiquitous phenomenon lacks a fundamental unders…
Compressible Air Entrapment in High-Speed Drop Impacts on Solid Surfaces
Yuan Liu, Peng Tan, Lei Xu
Using high-speed photography coupled with optical interference, we experimentally study the air entrapment during a liquid drop impacting a solid substrate. We observe the formatio…
