Behavior of alumina rafts at the bath-metal interface in an electrolysis cell have been simulated by a numerical model in previous studies. Further refinements on this model led to broader application and more « cell like» scenarios with its ability to consider three distinct bath metal interface phenomena. First, the transport wave who stem from disturbance in the electrolysis process such as bubbles, alumina deposits or crust-breakers actions is considered. Second, the stationary wave produced by the magnetohydrodynamics forces in the cell is replicated and third, the well-known permanent deformation of the bath-metal interface (BMI) is reproduced in the numerical model.
In addition to the aggregate’s movements and positions, the proposed model simulates the fragmentation and coalescence occurring on these alumina rafts. The purpose of this paper is to present an in-depth sensitivity analysis of the improved numerical model and identify scenarios and parameters which could affect industrial cell conditions.
