The purpose of this study was the optimization of an industrial furnace from a thermal point of view. Such a cylindrical furnace contains an Al-Mg molten alloy covered by a KCl-NaCl molten salt layer floating on it to prevent alloy evaporation.

When tilting the cylindrical furnace, it was necessary to compute the relation between the salt and alloy volumes and the area of the liquid alloy/salt layer interface for industrial purposes. Such a simple geometry depending on three variable parameters exhibits different aspects for different tilt angles.

This paper shows that COMSOL Multiphysics gives a straightforward solution to this 3D problem thanks to its numerical capabilities.
