摘　　要：本文基于成熟的火灾模拟方法,和建筑烟气扩散领域的理论及实验成果基础上,应用美国标准技术研究局开发的场模型工具FDS,对单室火灾进行了场模拟分析。结果显示:火源的释热率值、房屋的单室门窗状况等对着火房间内热值、烟气浓度以及温度场的分布特性的均有主要影响,随着火源释热率的增大,室内热烟气的温度迅速升高,而且房屋的通风面积越大,火灾发展越剧烈,上层热烟气温度越高,室内整体温度也越高。本文的研究结果对于房间内火灾控制具有一定的参考价值。Theoretical and experimental results of simulation-based method in this article is basea on proven Ilre, ana smoke-proliferation architecture, the application of the U.S. Bureau of Standards and Technology research tools developed field model FDS, carried out for a single room fire field simulation analysis. The results showed that： the heat release rate of the fire source value, the value of the fire room heat, have major impact on the distribution of gas concentration and temperature field house features a single room doors status, along with the source of fire heat release rate increases, indoor hot flue gas temperature rises rapidly, and the bigger house ventilation area, the more intense the fire development, the higher the upper hot gas temperature, the higher the overall temperature of the room. Results of this study for the fire control room have a certain reference value.
