The paper presents the research results of an experimental study of various parameters of magnetohydrodynamic mixing influence on silicon melt surface velocity. A technique has been developed for measuring the velocity of melt on the surface for various parameters of current through a system of inductors: amplitude, frequency, phase shift. Experimentally it was established that the dependences of melt mix ing rate on the frequency and phase shift of current have a maximum. The correlation of the results of mathematical modeling and experimental data on the influence of frequency, phase shift and current of a triangular shape on the velocity of silicon melt on the surface is shown. Mathematical modeling was carried out
using the COMSOL Multiphysics software package. Experimental studies were carried out on upgraded installation of directional crystallization GT-DSS450TM with an integrated system of magnetohydrodynamic mixing of silicon melt.
Key words: silicon, melt, magnetohydrodynamic mixing, mathematical modeling, melt speed, current strength, current frequency.
