N2 - Electrovortex flow (EVF) of liquid metal in container with submerged electrodes and bifilar current supply relates to problem of melt stirring in electrometallurgical aggregates like welding, electroslag remelting, direct current (DC) electrical arc furnaces (EAF) and others. Maximum values of electromagnetic (EM) force and flow velocity are developing in the region between electrodes. Sophisticated 3D flow patterns are forming around them. In presenting paper, the examples of measured electrical potential and 3D self-magnetic field of supplied DC in comparing with numerical calculation results as well as with quasi-2D model of EM fields are discussed. Several numerically computed 3D EVF patterns are presented for two regimes: i) laminar and ii) turbulent, which is obtained with LES (Large Eddy Simulation) approach. There is good qualitative and quantitative correspondence between experimentally obtained data and numerical computations results as well as with previously published results.
