基于FDS的基础模型火灾模拟研究
|
摘要
运用美国国家标准与技术研究院开发的FDS火灾动力学模拟软件,对一系列基础模型进行火灾场景模拟,分析比较温度、可见度、烟气浓度、CO_2浓度、CO浓度等指标的数值变化,研究结果,发现对于设定的单个模型的不同指标,可见度最先达到临界值,其次是温度;对不同模型的同一指标(温度)存在一定的内在规律。
Using FDS fire dynamics simulation software developed by National Institute of Standards and Technology, this article built a series of basic models for fire scenario simulation, to analysis temperature, visibility, soot concentration, CO_2 concentration, CO concentration, etc. The study found that for the different index in a single model, visibility first reach the critical value, temperature was the second. And for the same index in different models, such as temperature, there was a certain inherent law.
