A new device for the generation of microbubbles [Article]
(Elsevier, 2004)In this paper we present a new method for the production of bubble-liquid suspensions (from now on BLS) composed of micron-sized bubbles and with gas to liquid volume ratios larger than unity. We show that the BLS gas ...

Aerodynamically stabilized Taylor cone jets [Article]
(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 ...
