Abstract

Natural smoke extraction strategy in an atrium connecting a subway station and commercial building is numerically studied in this article. Different outdoor temperatures ranged from -10°C to 35°C during the fire-induced smoke development in the atrium are studied in detail. The t-square fire curve is assumed and the time averaged from 300s to 350s is adopted for quantitative comparisons of visibility and temperature profiles after HRR reaches the maximum 4MW. It is shown from the simulation results that the natural smoke extraction scheme is effective in the range of outdoor temperature from 35°C to 25°C. When the outdoor temperature decreases to 20°C, the effect of natural smoke extraction is less significant. After further decreasing to 10°C or lower, the natural smoke extraction scheme does not work anymore.
