Thermal Conductivity of Compounds Presen

This paper presents a database for the temperature-dependent thermal conductivity of compounds potentially present in the side ledge formed in aluminium electrolysis cells, which is critical for maintaining cell performance and longevity. The objective is to develop an analytical model with parameter sets for thermal conductivity across various compounds involved. The methodology employed utilizes a robust optimisation approach based on reliable models derived from fundamental physics, augmented by first-principles calculations in the absence of experimental data. The model parameters are optimized to align with the existing experimental observations, ensuring accurate predictions. The results indicate that for all compounds with available data, the model's predictions maintain a high degree of accuracy, closely matching reported experimental results. This comprehensive database serves as a significant resource for further research and development of numerical models in the field of aluminium electrolysis, addressing the lack of experimental thermal transport data for side ledge compounds. Thus, it offers valuable insights that could enhance the operational efficiency and service life of aluminium electrolysis cells.
