Аннотация: A three-dimensional mathematical model was developed to analyze the magnetohydronamic (MHD) processes and migration of discrete non-conductive particles in molten aluminium within an induction channel device. The particles' trajectories and dynamics of their distribution in metal were determined using the Lagrange approach with accПоказать полностьюount of the gravitational forces, drag forces, lift forces, added mass and electromagnetic force. The results indicate complex turbulence flows being present in the channels of the induction device caused by electromagnetic forces. The trajectories of particles and their dynamic distribution within the device channels are determined by the structure of hydrodynamic flows. The results show that the electromagnetic force present in the vertical channels of the device has a significant impact on removal of particles from the metal (especially of coarse particles). The study demonstrated that particles with the diameter of 50 µ m and more can be efficiently removed at 3 kW power in metal. Increase in power also has a positive effect on fine particles removal efficiency. For instance, the increase of power from 3 kW to 5 kW causes a 25 percent increase in 5 µ m particles removal efficiency. © 2022 IEEE.
