Estimate of air distribution in ventilation tunnel between subway station as function of piston effect

This article describes the numerical studies into air distribution in ventilation tunnel between subway stations. The studies aimed to determine regular air distribution patterns in the ventilation tunnel to formulate requirements for the filtration equipment operation. The relevance of the studies is conditioned by the fact that respirable dust content of subway air greatly exceeds the maximum allowable concentrations, which causes chronic respiratory diseases of passengers and, especially, subway personnel. The laws of change in the normal air velocity in the cross section of the ventilation tunnel and the structure of air flow along the height of the vent tunnel are determined for the mode of single train arrival at the station, which the most often event in subways. It is found that air distribution in the ventilation tunnel between subway stations during movement of trains is greatly nonuniform, namely, the air velocity direction is alternating, and the normal air velocity changes locally from 17.5 to +14.7 m/s, at the average value not higher than 2.4 m/s, at the train speed of 20 m/s. The normal air velocity distribution along the height is also highly nonuniform, which should be taken into account in engineering the air filtration equipment for vent tunnels. Based on the obtained results on air distribution, the arrangement requirements are set for the filtration equipment in ventilation tunnels between subway stations.

Keywords: subway, ventilation, air purification from dust, ring-shaped models, piston effect, air distribution, ventilation tunnel between subway stations, filtration equipment.
