Stabilization of the Algorithm to Compute the Magnetohydrodynamic Field Distribution in an Electrolysis Bath

Resumo

The article describes an algorithm that stabilizes the computation of a three-dimensional two-phase heterogeneous model of an aluminum electrolyzer based on a Navier–Stokes equation system. The computational stabilization method assumes zero total divergence of the mixture in the numerical region. This assumption smooths out the velocities of the different phases, which arise at the liquid–liquid mixing interface due to model idiosyncrasies. Results of computer experiments are reported.
