Influence of surfactant kinetics on rapid interface creation via microjet impact on liquid pools
D. Fernández-Martínez, E. J. Vega, J. M. Montanero +2
We experimentally investigate the influence of surfactant adsorption kinetics on cavity dynamics during the rapid formation of interfaces. For this purpose, we use a submillimeter…
Effect of a downstream vertical wall on the rise regime of an isolated bubble: an experimental study
T. González-Rubio, A. Rubio, R. Bolaños-Jiménez +1
This work experimentally investigates deformable nitrogen bubbles rising in ultrapure water and interacting with a vertical wall, focusing on how this downstream boundary alters th…
Critical bubble bursting in real water. Effect of surface-active contaminants
S. Rodríguez-Aparicio, A. Cebrián-García, E. J. Vega +2
We study the bursting of a bubble on a liquid free surface under critical conditions, i.e., those leading to the minimum (maximum) size (velocity) of the first-emitted jet droplet.…
A new emitter for electrospray and electrohydrodynamic jet printing
D. Fernández-Martínez, E. J. Vega, A. M. Gañán-Calvo +1
We propose using a dielectric beveled nozzle for electrospray and electrohydrodynamic jet printing. This nozzle stabilizes the liquid ejection of low-conductivity liquids, consider…
