In this paper, preliminary FDS fire chamber to simulate the flue gas generated through the corridor adjacent to the room near the migration laws, an analysis of indoor air flow field and the movement of smoke layer, and through the simulation of fire scenes, in a simple form of visual dynamic display of the entire process of fire, in the simulation process to obtain more accurate fire-related parameters such as temperature distribution, gas flow and heat radiation, and analysis of simulation results through the fire chamber of the flue gas migration characteristics, results showed that the chamber in the absence of fire smoke control measures, the process of the spread of smoke filled the first chamber is at the top, with the passage of time, the proliferation of slowly downward until the entire chamber is full, and then through the corridor smoke quickly spread to the nearby chamber.

本文运用FDS初步模拟了腔室火灾产生的烟气通过毗邻的走廊向附近房间迁移的规律，分析了室内空气流场和烟气层运动状况，并通过对火灾场景的模拟，以简单直观的形式动态显示出火灾发生的全过程，在模拟过程中获得较准确的火灾相关参数，如温度场分布，烟气流动及热辐射等，并通过模拟结果分析腔室火灾的烟气迁移特性，结果表明着火腔室在无防排烟措施的情况下，烟气扩散的过程是首先充满腔室顶部，随着时间的推移，慢慢向下扩散，直至将整个腔室充满，然后烟气通过走廊快速向附近腔室蔓延。
