Tóm tắt

The purpose of this study is to identify the mechanisms of formation of vortex structures in electrically conductive media under the effect of a magnetic field. An experimental set-up is created, and the selection of electrolytes as model fluids is justified. Procedures are developed for visualization of the processes of vortex formation and for measurement of the flow velocity field. In the experiments, we managed to obtain well reproducible and visualized patterns of a spiral vortex flow resulting in a large-scale swirl. A physical model for the generation of a large-scale vortex motion in electrically conductive fluids is proposed.
