Simulated computation and optimization of comprehensive physical fields in modern large-scale aluminium reduction cells

总结了国内外在铝电解槽电热场、热应力场及电磁流场方面的研究进展,指出当前多物理场仿真计算算法的不足,介绍了最新开发的“液(电解质)-液(铝)-气”和“液-气-固(颗粒)”两类三相流模型、多物理场(电、磁、热、流、力、浓度分布场等)、磁流体稳定性和电流效率三维耦合仿真模型与算法,并提出基于多相-多场耦合仿真的大型铝电解槽结构与生产工艺综合优化方法,发现大型铝电解槽在3.7～3.9 V低电压下高效、低电耗、低排放、稳定运行的状态空间,并确立相应的工艺实现条件.
