[HTML][HTML] Air entrainment dynamics of aqueous polymeric droplets from dilute to semidilute unentangled regimes

Z He, H Tran, MY Pack - Physics of Fluids, 2022 - pubs.aip.org
Recent studies have revealed the air-cushioning effect of droplet impact upon various
surfaces and although pure water droplets have extensively been studied, the air …

Drop impact on superheated surfaces: from capillary dominance to nonlinear advection dominance

P Chantelot, D Lohse - Journal of Fluid Mechanics, 2023 - cambridge.org
Ambient air cushions the impact of drops on solid substrates, an effect usually revealed by
the entrainment of a bubble, trapped as the air squeezed under the drop drains and liquid …

Characteristic rupture height of the mediating air film beneath an impacting drop on atomically smooth mica

R Kaviani, JM Kolinski - Physical Review Fluids, 2023 - APS
Before a droplet can contact a surface during impact, it must first displace the air beneath it.
Over a wide range of impact velocities, the droplet first squeezes the air into a thin film …

The skating of drops impacting over gas or vapour layers

P García-Geijo, G Riboux, JM Gordillo - Journal of Fluid Mechanics, 2024 - cambridge.org
We report numerical simulations confirming the predictions in Gordillo & Riboux (J. Fluid
Mech., vol. 941, 2022, A10), where we elucidated the lubrication mechanism by which a …

Wetting Dynamics Beneath an Impacting Droplet

R Kaviani - 2023 - infoscience.epfl.ch
Many natural and industrial processes involve fluid flow at a three phase interface between
liquid, solid and gas. When the liquid is forced to move rapidly over the solid surface, the …
