More than 35% of atria in Hong Kong can be classified as linear with large transverse dimensions. The smoke filling process due to fires in these atria was studied. Both the zone model and the computational fluid dynamics (CFD) field model were used. A linear atrium of volume 7,500 m3 was taken as an example. The multicell concept was used while simulating the smoke filling process with the zone model. Results were also justified by studying the smoke filling patterns in a scale model. The effects of the space volume on the smoke filling process was studied in three larger atria with volumes of 15,000, 22,500, and 30,000 m3. Finally, natural smoke-control systems, using horizontal ceiling vents in the first atrium, were studied.
