Bubble bursting in a sessile droplet
U. J. Gutiérrez-Hernández, B. Muñoz-Sánchez, A. Agúndez-Cruz +3
We analyzed experimentally and numerically the bursting of a bubble within a sessile droplet. Our experiments show that both sessile droplet curvature and confinement enhance the e…
Global linear stability of the bubble rising in the presence of a soluble surfactant
M. A. Herrada, J. M. López-Herrera, D. Fernández-MartÃnez +2
We study the stability of the bubble rising in the presence of a soluble surfactant numerically and experimentally. For the surfactant concentration considered, the Marangoni stres…
Stability analysis of the flow in a coflowing device
M. Rubio, S. RodrÃguez-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. RodrÃguez-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…
