NUMERICAL SIMULATION OF THE IMPACT OF VENTILATION MODE ON SUBWAY PLATFORM AIR DISTRIBUTION
In this paper, three-dimensional air flow distributions in a typical island platform under both natural and mechanical ventilation operation modes were simulated for the whole process of the train entering, staying in and departing from the platform. The mechanical ventilation modes include over-platform supply/under-platform exhaust (OSUE) and over-platform supply/over- platform exhaust (OSOE). Based on the data obtained from the simulations, the effects of natural and mechanical ventilation system on platform air distribution were analyzed. At last, the characteristics of air flow field under different ventilation mode and in different trains movement phase are concluded.
