Abstract
A numerical model of the cylindrical ingot melting process in an alternating magnetic field has been developed by coupling ANSYS and Fluent. The melting process was calculated using the ``enthalpy-porosity'' method and a turbulent flow k-ω SST unsteady model. Electromagnetic sources of motion and heat are defined by the method of harmonic problem finite elements on the magnetic vector potential in the ``inductor-ingot'' system at each iteration of the hydrodynamic problem. Based on the developed model, physical processes at the non-crucible melting of a titanium alloy (BT6) were calculated and analyzed. Figs 9, Refs 7.
