摘要：
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 oil the data obtained from the simulations, the effects of natural and mechanical ventilation system oil platform air distribution were analyzed. At last, the characteristics of air flow field under different ventilation mode and in different train's movement phase are concluded.
