Electromagnetic separation of impurities in a conductive medium

Abstract

A numerical study of the flow of an electrically conductive fluid is carried out in a cell under the action of a constant magnetic field. Distribution of electromotive force is investigated as well as the topology of electric current in the cell. The evolutions of velocity field are studied for different parameters. Two large scale unstable eddies are generated in the cell. The characteristic of the flow oscillations are determined using the wavelet analysis. It was found that an increase of current does not lead to the appearance of additional oscillation modes. Asymmetric pressure distribution may appear in the cell. Particle movement are possible due to the asymmetric pressure field.
