Abstract

A three-dimensional mathematical model of interconnected electromagnetic, hydrodynamic and thermal processes has been developed for an electromagnetic doser with induction current supply to the channel. By comparing with experimental data obtained for a prototype of a MHD installation for the production of lead pellets, a mathematical model of electromagnetic processes in the dosing unit was validated. Using mathematical modeling, physical processes in the system " dosing unit inductor - short-circuited channel with liquid metal - dosing unit magnet" were investigated. The electromagnetic and energy parameters of the dosing unit were determined, and the features of the thermal state of the liquid metal in its channel were established. Recommendations were formulated to reduce metal overheating in the channel during feeder operation. References 9, figures 10.
