Impulsive Hydrodynamic Exfoliation into Monolayer Graphene and Nanofragments by Transonic Flow Focusing
A. Ponce-Torres, A. Rubio-González, J. M. Montanero +2
We propose using Transonic Flow Focusing (TFF) to produce 2D and 0D nanomaterials. This technique focuses liquid suspensions into high-speed micrometer-scale jets, combining extrem…
Interface pinch-off in the presence of a soluble surfactant
M. Rubio, S. RodrÃguez-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…
The dominant role of jetting in micron- and sub-micron sea spray produced by bubble bursting: a revised model and comparison with measurements
Alfonso M. Ganan-Calvo, Miguel A. Herrada, Jose M. Lopez-Herrera
The primary physical mechanism governing the production of sub-micron sea spray aerosols (SSA) -- specifically the competition between film and jet droplets from bubble bursting --…
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…
Cone-jet Stokes solutions in strong viscous flows: the vanishing flow rate limit
Alfonso M. Ganan-Calvo, Miguel A. Herrada, Jens Eggers
Steady tip streaming in the vanishing flow rate limit has been evidenced both experimentally and numerically in the literature. However, local conical Stokes flow solutions support…
