LES modeling of heat and mass transfer in turbulent recirculated flows

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 os-cillations of the main flow eddies. Large Eddy Simulation (LES) of the turbulent melt flow in 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 simulation of heat and mass transfer processes in induction furnaces. Introduction Fluid flow in industrial metallurgical installations has be-come a subject of numerical modeling many years ago. The variety of geometries, boundary conditions, fluid forcing factors and a whole range of flow Reynolds numbers provide a good challenge for numerical investigations. The absence of an universal and always reliable modeling approach together with a wide choic
