Abstract
Experimental and numerical results on the influence of an external axial magnetic field on the structure of the electovortex flows are presented. Numerical calculations were carried out using various magnetohydrodynamic approximations. A comparison of the results obtained using electrodynamic and non-inductive approximations, as well as the results obtained when solving the complete MHD problem was made. The described methods can be used for simulation the structure of flows in the direct-arc-furnaces or in other electrometallurgical apparatus.
