Abstract Scope |
In this paper we demonstrate how we can develop a coarse-grained model for alumina distribution and dissolution in an aluminium reduction cell. The model is designed to have the potential of being a part of a control system or play the role of a Digital Twin. The framework is based on the concepts of Pragmatism in Industrial Modelling.The numerical grid is the coarsest possible and special numerical techniques, presented in the manuscript, are applied to support fast simulations. The bath flow is imported into the coarse-grained model, while dispersion and dissolution is resolved in the model. The physics of particulate alumina dissolution and the electrochemical consumption of dissolved alumina at the anodes is represented, allowing for observations of alumina distribution in time and space. In demonstration simulations the model is able to run up to 20 times faster than real time, depending upon resolution and level of physical details. |
