报告摘要：A big ministorage fire lasting for 108 hours occurred on 21 June 2016 in HongKong which killed two firefighters. Fire investigation were carried out by Computationa Fluid Dynamics (CFD) without clear indication with systematic full-scale burning tests.Because of storing so much combustibles in limited space, there challenges on the predicted results. Free CFD software is commonly used and there is no guarantee that the software isappropriate for simulating such big fires, Intermediate combustion reactions, thermal radiation and turbulence should be modeled properly with experimental supports. Problems identified in the application of CFD in simulating big enclosure fires will be discussed.

(2016年6月21日，香港发生了一起持续达108 小时的大型迷你仓库火灾，造成两名消防员殉职。该火灾事故的调查主要依靠计算流体力学(CFD)方法进行，但缺乏系统性的大尺度燃烧实验支持。由于在有限空间内储存了大量可燃物，预测结果面临诸多挑战。目前普遍使用免费的CFD软件，但这些软件是否适用于模拟如此大规模的火灾并无保障。燃烧反应、热辐射及湍流等关键物理过程的模拟需要实验数据的支撑。本报告将探讨在利用 CFD 模拟大型室内火灾时所面临的问题。)
