Abstract

In this paper, the ventilation characteristics of an underground parking lot with 17 buses has been investigated for two cases by computational fluid dynamics. It has been found that the average concentration of CO and $NO_x$ gas in the parking lot were 1.3 and 0.3 ppm respectively, when four buses operated. When the fifteen vehicles stopped in the parking lot, the average concentration of CO and $NO_x$ gas was 2.9 and 0.8 ppm respectively. The average concentration of two pollutants$(CO,\;NO_x)$ are lower than the standard values. Therefore the facilities and its location is proper to ventilation.
