Abstract

SCHNEIDER, André F. et al. Numerical and experimental results comparison of magnetic fields in aluminium eletrolysis cells. Rem: Rev. Esc. Minas [online]. 2008, vol.61, n.3, pp. 379-384. ISSN 0370-4467.  http://dx.doi.org/10.1590/S0370-44672008000300017.

Primary aluminum is produced in electrolytic cells where bath and metal flow due to Lorentz Forces. This work presents the experimental validation in real pots of a previously introduced 3-D magnetic field analysis methodology develop with the commercial Finite Element package ANSYS 9.0. Numerical results represent fairly the most important components for the simulated technology (BX and BY), considering the measurement error e. Maximum differences observed between experimental and numerical results are 33% for BX and 60% for BZ. Correlation between measured and calculated values are up to 98,8% for BX and 93,5% for BZ.

Keywords : Aluminum reduction; electrolytic pot; magnetic fields; magnetic field measurements; numerical simulation; magnetohydrodynamics.
