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， 为铁路列车火灾的控制和未来的全尺寸实验提供必要的基础
In this paper, the 1/5 scale model of the national standard YW22 carriage is taken as the research object. By using the flow field provided by the combustion wind tunnel to simulate the velocity field of the train during operation, the flue gas flow characteristics and temperature distribution in the train compartment are analyzed Experimental study The purpose of this paper is to explore the means and methods of simulating train scale experiments and to accumulate experience and experimental data to provide the necessary foundation for the control of railway train fires and future full-scale experiments
