Drop impact on viscous liquid films
When a liquid drop falls on a solid substrate, the air layer between them delays the
occurrence of liquid–solid contact. For impacts on smooth substrates, the air film can even …

Inertio-capillary rebound of a droplet impacting a fluid bath
LFL Alventosa, R Cimpeanu, DM Harris - Journal of Fluid Mechanics, 2023 - cambridge.org
The rebound of droplets impacting a deep fluid bath is studied both experimentally and
theoretically. Millimetric drops are generated using a piezoelectric droplet-on-demand …

The capture of airborne particulates by rain
Rain cleans pollution out of the atmosphere, as droplets collide with airborne particles
during free fall. Such particle–droplet collisions have been presumed to be capture events …

Similarity solutions in elastohydrodynamic bouncing
V Bertin - Journal of Fluid Mechanics, 2024 - cambridge.org
We investigate theoretically and numerically the impact of an elastic sphere on a rigid wall in
a viscous fluid. Our focus is on the dynamics of the contact, employing the soft lubrication …

Theoretical modeling of capillary surfer interactions on a vibrating fluid bath
We present and analyze a theoretical model for the dynamics and interactions of “capillary
surfers,” which are millimetric objects that self-propel while floating at the interface of a …

Drag on a partially immersed sphere at the capillary scale
We study the drag on a centimetric sphere in a uniform flow in the presence of a free surface
as a function of submergence depth. Through direct force measurements in a custom …

Impact of superhydrophobic sphere onto a pool covered by oil layer
We experimentally investigate the impact of a millimetric superhydrophobic sphere on a
water pool covered by a thin oil layer, with the aim of seeking the critical conditions for …

The role of body shape and mass in skimming on water
RA Palmer, FT Smith - Proceedings of the Royal Society …, 2023 - royalsocietypublishing.org
Over many years, there has been great practical interest in how solid bodies interact with
and skim on liquid layers. In the present investigation, the focus is on the important role of …

Surface tension force on a partially submerged horizontal concave cylinder
D Tan, F Zhang, X Zhou - Journal of Fluid Mechanics, 2022 - cambridge.org
A horizontal cylinder with a concave cross-section partially submerged in a liquid at a given
position may permit multiple menisci around itself. The number and stabilities of the menisci …
