Dynamic variables of drop impact such as force, drag, pressure, and stress distributions are
key to understanding a wide range of natural and industrial processes. While the study of …

Drop impact on solid surfaces widely occurs both in nature and engineering. In this
Perspective, we review the recent advances in experimental, theoretical, and numerical …

Suffering from poor robustness and durability, superhydrophobic surfaces are usually
difficult to be applied in practical engineering such as aircraft anti-icing and electricity …

Inertia-dominated droplet impact transfers momentum to a dry flat target within a short span
of time t characterized by (droplet diameter D)/(impact speed U). We investigate …

The transient force exerted by a low-speed liquid droplet impinging onto a flat rigid surface is
investigated experimentally. The measurements employ a high-sensitivity piezo-electric …

We investigate the dynamics of droplet impacts on a ring-decorated solid surface, which is
reported to reduce the integral of contact area over contact time by up to 80%. By using …

The impact of a low-speed droplet on a very-thin liquid film on a solid surface was analyzed
experimentally by observing the impact force and droplet behavior. A high impact force and …

Rainfall is a key driver of geomorphological processes ranging from impacting drops that
lead to the small-scale dislodgement of soil particles to large-scale morphogenic floods and …

In this study, the process of water droplet collision with a horizontal surface carrying a
deposited droplet and the impact forces caused by the Rayleigh jet in the retraction stage of …

Impacting drops are ubiquitous and the corresponding impact force is their most studied
dynamic quantity. However, impact forces arising from collisions with curved surfaces are …
