METHOD AND DEVICE FOR GENERATING FLUID MICROCURRENTS FOR THE PRODUCTION OF MICROBUBBLES, MICRODROPS, MICROEMULSIONS AND MICROCAPSULES

摘要

The invention relates to a method and device for generating fluid microcurrents for the production of microbubbles, microfoams, microdrops, microemulsions and microcapsules. The invention comprises a quasi-two-dimensional device, in which the inner thickness is noticeably smaller than the length and height thereof, comprising different inlet channels, along the thickness axis, for immiscible fluids which are introduced by means of pressure. The device also comprises one or more outlet channels which are perpendicular to the aforementioned inlet channels and which have a smaller section than that of the inlet channels. In addition, there are fewer outlet channels than inlet channels. The inner walls of the device take the form of surfaces comprising various smooth surfaces. According to the inventive method, the interfaces between the fluids inside the device are static and the surface tension forces are much greater than the rest of the mass forces.
