Presentation Title Modeling Gravity Wave in 3D with OpenFoam in an Aluminum Reduction Cell with Regular and Irregular Cathode Surfaces

On-Site Speaker (Planned) Marc Dupuis
Abstract Scope In recent years extensive modeling work have been done to assess if the usage of irregular cathode surface increases or not the MHD cell stability. So far 2 types of studies have been carried out: full 3D steady-state analysis and 2D shallow layer dynamic analysis. Cell stability being a transient phenomena, steady-state results are not providing any direct answer to the question. 2D shallow layer dynamic analysis can directly answer the question, but unfortunately, irregular cathode surface introduces a third dimension to the flow, so this type of 2D analysis is not the best suited to analyze this type of 3D flow problem. The current work presents a new way to analyze the problem and answer the question. Lateral gravity waves have been simulated in a 3D cell slice model using VOF formulation in OpenFoam. Results obtained for cell using or not irregular cathode surface are compared.
