This paper presents results of a project initiated by ASHRAE and the National Research Council of Canada. The project applies both physical and numerical modeling to atrium smoke exhaust systems to investigate the effectiveness of such systems and to develop guidelines for their design.

In this paper, results were obtained from a series of tests conducted using a large-scale physical model. The results from the physical model studies are used to investigate the effect of various parameters including fire size, volumetric flow rate for the smoke exhaust system, and the number and location of the exhaust inlets on the conditions in the atrium.
