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 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 ...

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 ...

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 ...

Self-similar electrohydrodynamic solutions in multiple coaxial Taylor cones
(2021)
We calculate analytically the self-similar Stokes flow driven by an externally applied electric field in a multiple coaxial Taylor cone consisting of an arbitrary number of immiscible leaky-dielectric or dielectric fluids. ...

On the physics of transient ejection from bubble bursting
(Cambridge University Press, 2021-12)
Using a dynamical scaling analysis of the flow variables and their evolution due to bubble bursting, here we predict the size and speed of ejected droplets for the whole range of experimental Ohnesorge and Bond numbers ...

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 ...
