CH-99-01-2 -- A CFD Analysis of Station Fire Conditions in the Buenos Aires Subway System PDF

This paper presents results of a study where computational fluid dynamics (CFD) was the numerical tool used to analyze the ventilation performance in stations of the Buenos Aires Metro subway system. Both natural and mechanical ventilation options were studied. The study showed that although natural ventilation was sufficient to maintain the temperature criteria, it presented a potential egress problem by letting hot gases leave through the entranceways. Mechanical ventilation, through the use of jet fans, solved this problem, purging the hot gases away from the fire and toward the tunnels.
