Abstract
The paper investigates the possibility to control the two-phase flow of immiscible liquids with a high viscosity ratio of the carrier and dispersed phases in a T-junction microchannel, with the dispersed phase being a ferromagnetic liquid, by means of a constant magnetic field. The effects of separation of slugs and microdroplets of a ferrofluid, as well as the controllability of the structure of the parallel flow of immiscible liquids, have been found. The obtained results may be used to design microfluidic systems in order to efficiently sort particles, as well as intensify heat and mass transfer processes.
期刊介绍：
The journal Thermophysics and Aeromechanics publishes original reports, reviews, and discussions on the following topics: hydrogasdynamics, heat and mass transfer, turbulence, means and methods of aero- and thermophysical experiment, physics of low-temperature plasma, and physical and technical problems of energetics. These topics are the prior fields of investigation at the Institute of Thermophysics and the Institute of Theoretical and Applied Mechanics of the Siberian Branch of the Russian Academy of Sciences (SB RAS), which are the founders of the journal along with SB RAS. This publication promotes an exchange of information between the researchers of Russia and the international scientific community.
