摘要

高速列车客室环境相对封闭，列车运行时，在送风方式和客室结构的综合影响下，空气污染物在流场中的传播特征复杂多变。本文基于具有完整空调系统、客室内装和风道结构的高速列车客室流场开展实车实验研究。结果表明，在客室中部产生的固态污染颗粒会造成上中下游污染物浓度不同程度的上升。其中，下游的污染物浓度上升最为剧烈。顶部送风模式相比于底部送风模式能够更好地抑制污染物在客室空间内的传播。最后，以静电除尘技术和介质阻挡放电技术为代表的空气净化技术能够显著提升客室空气污染物的净化效率，二者的空气净化效率和客室空气污染物浓度呈正相关，且静电除尘技术的空气净化效率优于介质阻挡放电技术。

Abstract

The passenger cabin of a high-speed train is relatively well-sealed. Thus the spreading characteristic of air pollutants within the cabin may vary significantly under operation due to the influence of different ventilation modes as well as the cabin layout structure. The present work conducted a systematic experimental study on the air pollutant spreading characteristic in the passenger cabin of a real high-speed train with a complete air condition system

wind passage structures and cabin decorations. The results indicate that

the air pollutants emerged in the middle of the passenger cabin can spread to both ends of the cabin

resulting in the increase of pollutant concentration to different levels at different locations. Particularly

the downstream can reach the highest pollutant concentration. The top air supply mode works better in restricting the air pollutant spreading than the bottom air supply mode. Two air purification techniques

i.e.

intense field dielectric (IFD) and dielectric barrier discharge (DBD)

can significantly increase the purification effect of air pollutants

and the effectiveness of air purification is positively correlated with the air pollutant concentration. Moreover

the IFD technique exhibits a better purification efficiency than that of the DBD technique.
