STUDY OF MAGNETOHYDRODYNAMICS STABILITY OF AN ALUMINUM REDUCTION CELL |
| |
| Abstract: | Stability of an aluminum reduction cell is one of the key technologies in the aluminumelectrolyte industry. This paper reviews its historical development, current status and new advancesin the past two decades. The physical phenomenon of reduction cell stability and the mechanismof magneto-hydrodynamics stability are explained. The mathematical definition and criteria ofstability are given. This paper also presents 2D and 3D mathematical models and numericalmethods for stability analysis(finite element method and spectral method). Finally, a stabilityanalysis of a 230KA reduction cell is carried out in this paper. |
