| Abstract Scope |
A mathematical model has been developed to reproduce the tridimensional interface between bath and metal in an electrolysis cell. In the last year, the mathematical model has been adapted to consider alumina rafts movements in tridimensional coordinates. Among the geometrical challenges inherent to such improvement, it was necessary to properly introduce concepts such as “stream”, “interfacial forces”, and “buoyancy force”. Hence, the model uses interfacial phenomena to reproduce the movement of alumina raft at the bath-metal interface. The potential of such tracking is shown under different cell condition. In order to achieve an accurate reproduction of real cell condition, it is necessary to validate the correct behavior of the model following these recent changes. This paper detail the scope of the modifications applied to the model, the validation steps necessary to assure an appropriate level of reliability and show the raft tracking potential for industrial application. |
