Computational fluid dynamics (CFD) modeling is a useful tool to gain an insight into various high temperature metallurgical processes such as the magnesium refining and the magnesium solid oxide membrane (SOM) electrolysis. In both processes, argon gas was used to stir the molten salt (flux) in order to improve the transport of magnesium vapor out of the flux and achieve chemical homogeneity in the molten flux. In this study, the flow behavior of the flux and its effect on the mass transport of magnesium were simulated, and the flow behavior of the flux under reduced pressure stirred by argon was also investigated using COMSOL multiphysics. An optimized design of the magnesium production system was proposed based on the modeling results.
