Electrovortex liquid metal flows in cells with localized current supply

The paper studies the flow of a liquid metal in a cylindrical cell caused by the action of electromagnetic force. An electric current passes through the metal. The current is locally supplied to the area at the bottom of the cell and discharged at the top. Force generates from the joint action of an electric current and its own magnetic field. The vorticity of the force is nonzero and an electro-vortex flow (EVF) arises. The characteristics of the intensity and oscillations of EVF are studied numerically and experimentally. Methods for contactless determination of the position of the liquid metal boundary have been developed. The possibility of manipulation of the intensity and shape of EVF was studied.
