摘要

采用计算流体力学(CFD)方法对澳大利亚新南威尔士州帕克斯的一场房屋火灾中固体可燃材料的燃烧过程进行了重建。实验是在一个装有多种可燃材料的隔间室内进行的,并确定了火源。通过现场可视化以及与计算的热释放率的比较,观察到涉及火焰和烟雾蔓延的大规模火灾发展,导致无法维持闪络条件。通过数值模型捕捉了从实验镜头中获取的重要瞬态火灾事件,包括火焰在沙发和地毯等家具上的蔓延。目前的模拟和实验研究正在被用作消防员在线消防培训计划的组成部分。

Fire scene reconstruction of a furnished compartment room in a house fire

Computational fluid dynamics (CFD) has been employed to reconstruct the burning of solid combustible materials of a house fire in Parkes, New South Wales, Australia. Experiment was conducted in a compartment room containing multiple combustible materials with an identified ignition source. Large scale fire development involving the spread of flame and smoke leading to the untenable condition of flashover was observed from on-site visualisations as well as comparison to calculated heat release rates. Significant transient fire events taken from experimental footages including the spread of flame on furniture such as couch and carpet were captured through the numerical model. The present simulation and experimental studies are currently being utilised as components for online fire training program for fire-fighters.
