Droplet impact
A liquid droplet impinging on a solid surface is a ubiquitous and essential process both in Nature and in technology. The interplay of several parameters, including liquid type, surface property, and surrounding gas, often produces surprising outcomes and obscures underlying mechanism. With high-speed-imaging, we experimentally study drop impact on micro-and-nano- structured superhydrophobic surfaces, with a focus on the effects of small-scale roughness, impact velocity, and air pressure.
