Formation and Dynamics of Droplets in a Magnetic Fluid in Microchannels in an Inhomogeneous Magnetic Field of a Ring Magnet
A study was made of the dynamics of nonmagnetic droplets in magnetic fluids in microchannels with the flow-focusing configuration under the action of an inhomogeneous magnetic field of a ring magnet. Two types of multiphase systems were investigated: nonmagnetic emulsions “oil in water,” “water in oil,” and “water in oil in water,” as well as magnetic oil-in-water emulsions in which the magnetic fluid was used as the continuous phase. Characterization was made of the dependences of the sizes of the generated nonmagnetic inclusions on the flow rate of the continuous magnetic phase and on the displacement of the magnetic field source relative to the dispersed phase supply connector horizontally along the channel axis are obtained.
期刊介绍：
Bulletin of the Russian Academy of Sciences: Physics is an international peer reviewed journal published with the participation of the Russian Academy of Sciences. It presents full-text articles (regular, letters to the editor, reviews) with the most recent results in miscellaneous fields of physics and astronomy: nuclear physics, cosmic rays, condensed matter physics, plasma physics, optics and photonics, nanotechnologies, solar and astrophysics, physical applications in material sciences, life sciences, etc. Bulletin of the Russian Academy of Sciences: Physics focuses on the most relevant multidisciplinary topics in natural sciences, both fundamental and applied. Manuscripts can be submitted in Russian and English languages and are subject to peer review. Accepted articles are usually combined in thematic issues on certain topics according to the journal editorial policy. Authors featured in the journal represent renowned scientific laboratories and institutes from different countries, including large international collaborations. There are globally recognized researchers among the authors: Nobel laureates and recipients of other awards, and members of national academies of sciences and international scientific societies.
