摘　　要：本文分析铁路列车车厢火灾的主要特点,基于Phoenics软件采用CFD方法对列车车厢火灾引发的烟气流动进行数值模拟,建立SKE-2000电动车组的一节车厢的内部模型,并对其材料和边界,火源和烟气流动模型进行设置。计算分析车厢内部火灾时烟气扩散过程,车厢空间各区域烟气浓度分布情况,温度的分布及变化趋势,并讨论分析紧急状况下烟气和温度变化对列车人员疏散的影响。In this paper, the main characteristics of the high-speed rail train compartment fire would be analyzed, and CFD method would be adopted to simulate the smoke＇s flow caused by train compartment fire based on the Phoenics software, and then a model of one compartment＇s internal space of the SKE-2000 EMUs shall be established, and the parameters of the materials, the boundary, the fire and smoke flow model would be set. At the same time, the smoke＇s diffusion process, smoke＇s concentration distribution, the distribution and changing trend of temperature in compartment during internal fire shall be calculated and analyzed. At last, the impact of smoke and temperature＇s changing to train evacuation on emergency should be discussed in this paper.
