火灾中木耳燃烧特性及数值模拟

Combustion Characteristics and Numerical Simulation of Agaric in Fire

从基础研究角度出发,针对湖南衡阳“11．3”特大火灾事故的重要可燃物木耳,应用符合ISO 9705标准的ISO ROOM装置对其进行全尺寸实验研究,并测量包括热释放速率、质量损失速率、房间内温度场、组分浓度等多个参量．同时对该过程进行了计算机数值模拟,计算结果与实验数据具有较好的一致性,为下一步对衡阳“11．3”整个火灾场景进行数值模拟研究提供了基础．

Agaric, an important combustible material in Hengyang ＂11.3＂ big fire of Hunan Province was studied in a fullscale room in accordance with ISO 9705, from the viewpoint of basic research. Multi-parameters, such as heat release rate, mass loss rate, temperature field, and species concentration, were measured. At the same time, this process was numerically simulated. The computational results were consistent with experimental data, which establishes a good foundation for simulation of the whole Hengyang ＂11.3＂ big fire.
