Optimization of Multi-Stack Exhaust Systems - New System Design Application

Both analytical and numerical optimization methods have been developed to optimize multi-stack exhaust systems for application in new system designs. In these systems the combined airflow capacity of the stacks equals the maximum laboratory exhaust airflow. The theoretical analysis indicates that the optimized design uses as little as 50% of the design fan power annually. This paper presents the system models, the optimization methods, and describes appropriate applications.
