Interface pinch-off in the presence of a soluble surfactant
M. Rubio, S. Rodríguez-Aparicio, J. M. Montanero +1
We study numerically and experimentally the breakup of a pendant droplet loaded with a soluble surfactant. We consider the limit in which surfactant sorption is limited only by dif…
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.…
Stability analysis of the flow in a coflowing device
M. Rubio, S. Rodríguez-Aparicio, M. G. Cabezas +2
We analyze the stability of the coflow configuration. The experiments and the global stability analysis show that the emitted jet always destabilizes before the tapering conical me…
A novel microfluidic method to produce monodisperse micrometer bubbles
A. Rubio, S. Rodríguez-Aparicio, J. M. Montanero +1
We present a novel microfluidic method to produce quasi-monodisperse bubbles with diameters from tens to very few microns. A gaseous rivulet flows over the shallow groove printed o…
