Abstract

Language:

This study investigates the in-depth characteristics of ledge heat transfer in an aluminium cell through a water-model setup. The objective was to develop a heat transfer probe capable of quantitatively measuring heat transfer at various locations within a fill-scale 3-D air-water model under different operational conditions. A combination of experimental measurements and similitude analysis allowed for the correlation of the observed data with existing literature. The results revealed a significant range of heat transfer coefficients pertinent to the reduction cell, reflecting variations influenced by factors such as anode bottom inclination and vertical positioning on the side ledge relative to the anode slot. Through this research, a suggested range of heat transfer coefficients is provided, contributing valuable insights for enhancing cell design and operation to achieve optimal thermal management in aluminium production facilities. Understanding the thermal dynamics within the side ledge is crucial for maintaining steady-state operation and maximizing service life, underscoring the importance of rigorous heat transfer evaluations in the context of industrial applications.
