摘要：
The paper deals with numerical analysis of low frequency and turbulent oscillations of the temperature field in an industrial induction channel furnace (ICF) with different designs of the channel - symmetrical and asymmetrical with one widened branch. The turbulent heat and mass exchange in the melt is calculated using a 3D electromagnetic (EM) model and a 3D transient Large Eddy Simulation (LES) approach. Long-term computations for the industrial ICF have been performed for the first time. Oscillations of the temperature maximum and its position in the ICF channel are considered. Averaged flow velocity and temperature field distributions are discussed and qualitative distributions of turbulent kinetic energy for re-circulated flows in different magnetohydrodynamic devices are compared.
