The paper presents the features of mathematical modeling of magnetohydrodynamic mixing system of silicon melt of GT-DSS450TM experimental installation of directional crystallization. The aim of this work is to search for optimal current pulse shape in MHDF inductors and to estimate the influence of pulse shape and phase shift on the mixing efficiency of silicon melt. A series of calculations were carried out and the effect of current pulses in sinusoidal and triangular inductors on the efficiency of MHD mixing and maximum rate of silicon melt on the surface and in the volume was estimated. The distribution of the Lorentz forces in the volume of silicon melt during the flow of current pulses of various shapes through inductors is estimated. The studies were carried out by the method of mathematical modeling using the COMSOL Multiphysics software package.
Key words: mathematical modeling, silicon, magnetohydrodynamic mixing, phase shift, current pulse shape.
