Fast droplet impact onto slowly moving deep pools
Thomas C. Sykes, Luke F. L. Alventosa, J. Rafael Castrejon-Pita +3
When a fast droplet impacts a pool, the resulting ejecta sheet dynamics determine the final impact outcome. At low Capillary numbers, the ejecta sheet remains separate from a deep…
Predicting liquid properties and behavior via droplet pinch-off and machine learning
Jingtao Wang, Qiwei Chen, C Ricardo Constante-Amores +3
Here we demonstrate that the time-evolving interface observed during droplet formation, and consequently the resulting morphology nearing pinch-off, encode sufficient physical info…
Bouncing to coalescence transition for droplet impact onto moving liquid pools
Daniel M. Harris, Luke F. L. Alventosa, Oliver Sand +5
A droplet impacting a deep fluid bath is as common as rain over the ocean. If the impact is sufficiently gentle, the mediating air layer remains intact, and the droplet may rebound…
A new flow-based design for double-lumen needles
Radu Cimpeanu, Alfonso A. Castrejon-Pita, Lee Nai Lim +2
Oocyte retrieval forms a crucial part of in vitro fertilisation treatment and its ultimate outcome. Standard double-lumen needles, which include a sequence of aspiration and flushi…
Impact of droplets onto surfactant-laden thin liquid films
C. R. Constante-Amores, L. Kahouadji, S. Shin +5
We study the effect of insoluble surfactants on the impact of surfactant-free droplets on surfactant-laden thin liquid films via a fully three-dimensional direct numerical simulati…
Direct numerical simulations of turbulent jets: vortex-interface-surfactant interactions
C. R. Constante-Amores, T. Abadie, L. Kahouadji +5
We study the effect of insoluble surfactants on the spatio-temporal evolution of turbulent jets. We use three-dimensional numerical simulations and employ an interface-tracking/lev…
