Focusing liquid microjets with nozzles
(IOP Publishing Ltd, 2012)
The stability of flow focusing taking place in a converging–diverging nozzle, as well as the size of the resulting microjets, is examined experimentally in this paper. The results obtained in most aspects of the problem ...

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 ...

Numerical simulation of electrospray in the cone-jet mode
(American Physical Society, 2012)
We present a robust and computationally efficient numerical scheme for simulating steady electrohydrodynamic atomization processes (electrospray). The main simplification assumed in this scheme is that all the free ...

The production of viscoelastic capillary jets with gaseous flow focusing
(Elsevier, 2016)
The production of viscoelastic capillary jets with gaseous flow focusing is studied experimentally. In this technique, the liquid is injected at a constant flow rate through a feeding capillary located in front of the ...

A new flow focusing technique to produce very thin jets
(IOP Publishing Ltd, 2013)
A new technique is proposed in this paper to produce jets, droplets, and emulsions with sizes ranging from tens of microns down to the submicrometer scale. Liquid is injected at a constant flow rate through a hypodermic ...

Transonic flow focusing: stability analysis and jet diameter
(Elsevier Ltd, 2021)
We study numerically and experimentally the stability of the transonic flow focusing used in serial femtosecond crystallography (SFX) to place complex biochemical species into the beam focus. Both the numerical and ...

Monosized dripping mode of axisymmetric flow focusing
(American Physical Society (APS), 2016)
We identify and analyze the perfectly regular dripping mode of flow focusing. This mode occurs within narrow intervals of injected flow rates and applied pressure drops and leads to homogeneous-size droplets with ...

Electrical Conductivity of a Stretching Viscoelastic Filament
(MDPI, 2021)
Long polymeric chains highly stretched and aligned with the flow confer a strong mechanical anisotropy on a viscoelastic solution. The electrically-driven transport of free ions under such conditions is far from being ...

Infuence of the surface viscous stress on the pinch‑of of free surfaces loaded with nearly‑inviscid surfactants
(Nature Research, 2020-09)
We analyze the breakup of a pendant water droplet loaded with SDS. The free surface minimum radius measured in the experiments is compared with that obtained from a numerical solution of the Navier–Stokes equations for ...
