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) ...

The onset of electrospray: the universal scaling laws of the first ejection
(Nature Publishing Group, 2016)
The disintegration of liquid drops with low electrical conductivity and subject to an electric field is investigated both theoretically and experimentally. This disintegration takes place through the development of a ...

Electrokinetic effects in the breakup of electrified jets: A Volume-Of-Fluid numerical study
(Elsevier, 2015)
The breakup of a charged liquid column is studied numerically using Volume-OF-Fluid (VOF) for a range of timescales where electrokinetic phenomena may become significant, i.e when the time to breakup becomes comparable ...

Absolute and convective instability of a charged viscoelastic liquid jet
(Elsevier, 2013)
The absolute and convective instability of an electrically charged viscoelastic liquid jet is studied. The liquid is assumed to be (i) a dilute polymer solution described by the Oldroyd-B viscoelastic model, and also and ...

Experimental and Numerical Studies on Microfluidic Systems
(2016-04-21)
The work presented in this thesis can be summarized as a compilation of five different and comprehensive studies in the field of microuidic ows, related to the formation of jets, drops and bubbles; where the surface tension ...

Novel swirl flow‑focusing microfluidic device for the production of monodisperse microbubbles
(Springer, 2018-08)
A novel swirl flow-focusing microfluidic axisymmetric device for the generation of monodisperse microbubbles at high production rates to be used as in-line contrast agents for medical applications is presented. The swirl ...

The natural breakup length of a steady capillary jet
(Bulletin of the American Physical Society, 2019)
Despite their fundamental and applied importance, a general model to predict the natural breakup length of steady capillary jets has not been proposed yet. In this work, we derive a scaling law with two universal constants ...
