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 ...

The role of charge relaxation in electrified tip streaming
(AIP Publishing, 2023-01-24)
We study experimentally and numerically the onset of tip streaming in an electrified droplet. The experiments show that, for a sufficiently small dimensionless conductivity, the droplet apex oscillates before ejecting a ...

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 ...

Diameter and charge of the first droplet emitted in electrospray
(American Institute of Physics Inc., 2021)
The first droplet produced by a low-conductivity pendant/sessile droplet subject to a strong electric field is particularly important at the fundamental level because, in contrast to steady electrospray phenomena, its ...

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 ...

Effect of an axial electric field on the breakup of a leaky-dielectric liquid filament
(American Institute of Physics Inc., 2021)
We study experimentally and numerically the thinning of Newtonian leaky-dielectric filaments subjected to an axial electric field. We consider moderately viscous liquids with high electrical permittivity. We analyze the ...

Stability and tip streaming of a surfactant-loaded drop in an extensional flow. Influence of surface viscosity
(Cambridge University Press, 2022-03)
We study numerically the nonlinear stationary states of a droplet covered with an insoluble surfactant in a uniaxial extensional flow. We calculate both the eigenfunctions to reveal the instability mechanism and the ...
