Controlled cavity collapse: scaling laws of drop formation
(Royal Society of Chemistry (RSC), 2018-09)
The formation of transient cavities at liquid interfaces occurs in an immense variety of natural processes, among which the bursting of surface bubbles and the impact of a drop on a liquid pool are salient. The collapse ...

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 ...

Aerodynamically stabilized Taylor cone jets
(American Physical Society, 2019)
We introduce a way to produce steady micro/nano-liquid jets via electrohydrodynamic elds together with co- owing gas streams. We study the dripping-jetting transition of this con guration theoretically through a global ...

Generation of small mono-disperse bubbles in axisymmetric T-junction: The role of swirl
(American Institute of Physics Inc., 2011)
The dynamics of micro-bubble formation in an axisymmetric T-junction for a gas-liquid system is analyzed. The approach adopted involves the creation of a tapering gas-liquid meniscus from which a steady gas ligament ...

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 ...

Vortex breakdown in a water-spout flow
(AIP Publishing, 2013)
The numerical study of the steady axisymmetric air-water flow in a vertical sealed cylinder, driven by the rotating top disk, describes topological transformations as the rotation intensifies. The air meridional flow (AMF) ...

Cavity losses estimation in CSP applications
(American Institute of Physics, 2018)
Estimations of convection and radiation cavity losses in two common CSP applications have been analyzed; a cavity in a solar tower plant for high temperature (800 K) and in a down facing cavity in a Fresnel configuration ...

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 ...
