摘要
The invention relates to a method for producing simple and compound emulsions having micrometre-sized, controllable diameters and coatings, using a device formed by elements having characteristic dimensions of the order of a millimetre. The emulsions are produced using the suction produced by the flow of a viscous liquid through the section of a millimetre-sized capillary tube. According to a parametric analysis, the liquid or the pair of liquids to be emulsified form a simple or compound steady capillary jet of micrometre diameter, by the action of the co-flow of the emulsifying liquid and the favourable pressure gradient produced. The jet breaks because of capillary instability, forming simple or compound monodisperse micro-drops. The invention disclosed in this description can be used in industrial sectors where the production of simple and compound, monodisperse, homogeneous emulsions having micrometric-sized, controllable diameters and coatings is an essential part of the process.
