Abstract
A comprehensive program (ARC/DYNAMIC) was developed to simulate the dynamic behavior of Al reduction cells during operation. The program uses the mass and energy balance equations to determine the transient evolution of > 60 process variables. In addition, it simulates various operational and control policies in use during cell operation. This paper describes the use of ARC/DYNAMIC to study the sensitivity of cell dynamic response to the BEMF. A description of the steady state solve and the amperage fluctuation model implemented in the program is presented.
