Abstract
A generalized, nondimensional relationship for flow through defined narrow gaps is used to predict leakage flow past closed door assemblies. Typical gap shapes considered include straight-through; single or double sharp (90°) bends; baffle at leading edge; comb-type labyrinth; and filament brush seal. Applications for prediction and design appropriate to smoke control systems are indicated.
