Global stability analysis of axisymmetric liquid-liquid flow focusing
(Cambridge University Press, 2020)
We analyse both numerically and experimentally the stability of the steady jetting tip streaming produced by focusing a liquid stream with another liquid current when they coflow through the orifice of an axisymmetric ...

Self-similarity in the breakup of very dilute viscoelastic solutions
(Cambridge, 2020)
When pushed out of a syringe, polymer solutions form droplets attached by long and slender cylindrical filaments whose diameter decreases exponentially with time before eventually breaking. In the last stages of this ...

The ocean fine spray
(AIP Publishing, 2023-02-10)
An important fraction of the atmospheric aerosols comes from the ocean spray originated by the bursting of surface bubbles. A theoretical framework that incorporates the latest knowledge on film and jet droplets from bubble ...

Droplet group production in an AC electro- flow focusing microdevice
(Springer, 2017-09)
We report the production of droplet groups with a controlled number of drops in a microfluidic electro-flow focusing device under the action of an AC electric field. This regime appears for moderate voltages (500-700 V ...

Global stability analysis of bubbles rising in a vertical capillary with an external flow
(Cambridge University Press, 2023)
We study the linear stability of bubbles in a capillary tube under external flow. Yu et al. (J. Fluid Mech., vol. 911, 2021, pp. 1-19) showed that a rich variety of bubble dynamics occurs when a downward external flow is ...

Megahertz pulse trains enable multi-hit serial femtosecond crystallography experiments at X-ray free electron lasers
(Springer Nature, 2022)
The European X-ray Free Electron Laser (XFEL) and Linac Coherent Light Source (LCLS) II are extremely intense sources of X-rays capable of generating Serial Femtosecond Crystallography (SFX) data at megahertz (MHz) ...

Electrokinetic modelling of cone-jet electrosprays
(Cambridge University Express, 2023)
The physics of electrospray has been subject to an intense debate for three decades regarding the ultimate electrokinetics that determines the electric current and the size of the emitted droplets in the steady Taylor ...

Regular and complex singularities of the generalized thin film equation in two dimensions
(Cambridge University Press, 2021)
We use a generalized version of the equation of motion for a thin film of liquid on a solid, horizontal substrate as a model system to study the formation of singularities in space dimensions greater than one. Varying ...

Breakup length of AC electrified jets in a microfluidic flow‑focusing junction
(Springer, 2015-06)
Electroactuation of liquid-liquid interfaces offers promising methods to actively modulate droplet formation in droplet-based microfluidic systems. Here, flow-focusing junctions are coupled to electrodes to control droplet ...

Development of an automatic test bench to assess sprinkler irrigation uniformity in different wind conditions. Computers and Electronics in Agriculture
(Elsevier, 2018)
In sprinkler irrigation the water distribution uniformity in field conditions is not always a known factor, mainly due to the many variables involved, especially the wind. The main objective of this study was to design, ...
