- Abstract
- Terminals are often fitted to chimneys, flues and ventilation exhausts specifically to increase air movement and prevent wind-induced flow-reversal. This paper discusses the performance of several terminal designs. Such information can be used as a basis for system designers to select terminals for particular applications, ensuring terminal behavior is matched to system requirements. This matching should lead to more efficient mechanical ventilation systems, passive stack systems with greater air-moving capabilities, and chimneys and flues that are protected against flow-reversal. The data may also be used by terminal manufacturers as a comparison test.
