摘　　要：本文以国标ＹＷ２２车厢的１／５ 缩尺模型为研究对象，利用燃烧风洞提供的流场模拟列车运行时的速度场， 对运行列车车厢内发生火灾时的烟气流动特性和温度场分布进行了实验研究。本文的目的在于探索运行列车缩尺实验的模拟手段和方法， 并积累经验和实验数据，The experimental simulation has been performed with the 1/5 reducedscale model of a sleeping carriage to investigate the smoke flowing properties.The speed field of the running train is simulated making use of the wind provided in the combustion wind tunnel of the state key lab of fire science,USTC.The fire smoke properties and the temperature field in the sleeping carriage are emphasized in the paper.The purpose of this paper lies in investigating the simulation method of reduced scale experiment on the running train and accumulating experience and data in order to provide a basis for the experiment centering on controlling running train fire safety and for a full scale experiment in the future.
