We report a method to generate steady coaxial jets of immiscible liquids with diameters in the range of micrometer/nanometer size. This compound jet is generated by the action of electro-hydrodynamic (EHD) forces with a diameter that ranges from tens of nanometers to tens of micrometers. The eventual jet breakup results in an aerosol of monodisperse(More)
In this paper we present a new method for the production of bubble-liquid suspensions ͑from now on BLS͒ composed of micron-sized bubbles and with gas to liquid volume ratios larger than unity. We show that the BLS gas fraction ␭ϭQ g /Q l , being Q g and Q l the flow rates of gas and liquid, respectively, is controlled by a dimensionless parameter which(More)
The circulatory system of living organisms is an autonomous mechanical system softly tuned with the respiratory system, and both developed by evolution as a response to the complex oxygen demand patterns associated with motion. Circulatory health is rooted in adaptability, which entails an inherent variability. Here, we show that a generalized N-dimensional(More)
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 conical cusp that eventually ejects an ultrathin liquid ligament. A first tiny drop is emitted from the end of this ligament. Due to its(More)
