摘    要:
为获得微重力环境下载人航天器密封舱内火灾发生时的流场分布规律,建立简化的密封舱模型,利用FDS软件对不同火源位置、通风场景下的火灾进行了数值仿真,得到了烟气温度、浓度分布规律。仿真结果可为密封舱内火灾探测器的合理安装布局提供参考。

关 键 词:载人航天器   密封舱   微重力   火灾   流场   仿真研究

Abstract:
A sealed cabin model was established to obtain flow-field distribution laws in case of a fire in manned spacecraft under micro-gravity environment. FDS software was used to simulate fires under different location and ventilation. The distribution of smoke temperature and soot density were gained. The results can be a reference for installation of fire detectors in sealed cabins.
Keywords:manned spacecraft  sealed cabin  micro-gravity  fire  flow-field  simulation study
