The Flow of Liquid Metal in the MHD-Stirrer for Cylindrical Moulds

摘要

We study the operation of the MHD stirrer in a cylindrical channel with a liquid metal based on the results of experiments and 3D numerical simulations.The investigations described in this paper are focused on electromagnetic and hydrodynamic processes.We studied the forces acting on cylinders of different height placed inside the stirrer and calculated the intensity of electromagnetic forces as a function of the value and frequency of the feeding current.Experimental investigations of the velocity field and its oscillations in a cylindrical crucible filled with a gallium alloy were performed using ultrasonic Doppler velocimeter measurements.
