Large impact velocities suppress the splashing of micron-sized droplets
(American Physical Society, 2021)
Here we investigate the transition from spreading to splashing of drops with radii R varying from millimeters to tens of microns impacting onto a smooth and dry partially wetting substrate at normal atmospheric conditions. ...

On the jets produced by drops impacting a deep liquid pool and by bursting bubbles
(Cambridge University Press, 2021)
Here we provide a unified theoretical description of two different physical situations in which liquid jets are expelled out of the bulk of a liquid as a consequence of the capillary collapse of a void. We demonstrate ...

The initial impact of drops cushioned by an air or vapour layer with applications to the dynamic Leidenfrost regime
(Cambridge University Press, 2022-06-25)
This work is devoted to the study of the conditions under which a drop directed normally towards a superheated or isothermal smooth substrate prevents the initial contact with the solid by skating over a micrometre-sized ...

Theory of the jets ejected after the inertial collapse of cavities with applications to bubble bursting jets
(American Physical Society, 2023)
The dynamics of the axisymmetric jets originated from the bursting of bubbles in a liquid of density ρ, viscosity μ, and interfacial tension coefficient σ can be rationalized as a two-stage process in which, initially, the ...

Spreading and splashing of drops impacting rough substrates
(Publisher Cambridge University Press, 2021)
Here, we present experimental results of water and ethanol drops of radii R, density ρ and interfacial tension coefficient σ, impacting with a velocity V over different types of sandpapers containing particles of ...

Sistema agitador y difusor de un gas en líquidos
(Oficina Española de Patentes y Marcas , 2018-04-09)
Sistema agitador y difusor de un gas en líquidos que comprende un eje rotatorio, accionado por un sistema motriz de velocidad variable a voluntad y una o más palas unidas al eje rotatorio. La sección transversal de las ...

The skating of drops impacting over gas or vapour layers
(Cambridge University Press, 2024-06)
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 drop of a low-viscosity liquid impacting over ...
