Abstract
Experimental results show that heat and mass transfer processes in the turbulent melt flow of induction furnaces are significantly influenced by low-frequency large scale osillations of the main flow eddies. Large Eddy Simulation (LES) of the turbulent melt flow in an induction crucible furnace carries out with good conformity the transient three- dimensional oscillations of the dominating toroidal flow eddies. This 3D transient model offers new possibilities for simulating heat and mass transfer processes in induction furnaces. Tables 3, Figs 7, Refs 7.
