Modeling and experimental investigations on disturbing currents potential with a high-temperature fluid field

The studied objects of this article are the liquid non-metallic high temperature environments. Many important theoretical and practical technological problems haven't been solved yet, and these environments are the main ones for the area. For example, it hasn't been resolved yet how to achieve a stable position of liquid in the molten bath at a constant current in steel industry. The calculation of electromagnetic forces which play a decisive role in this case usually begins with calculation of the electric potential. The calculating tool is the software Matlab. Computer experiment revealed the significant heterogeneity of potential field on a liquid surface. Although the nature of its distribution on the surface scarcely depends on the Laplacian value, it depends very much on the boundary conditions of Dirichlet and Neumann.
