Numerical results show that, in all the cases analyzed, the introduction of swirl into the focusing liquid stabilizes the tapering gas-liquid meniscus from which a steady gas ligament issues. Consequently, a drastic reduction in the size of bubbles generated by the device is achieved under similar gas and liquid flow ratesapplication/pdf8 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Microfluidic flow-focusing deviceFluid bubblesVortex dynamicsinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess10.1063/1.31235335465508
