摘　　要：流淌火灾害会对环境、社会、经济等造成巨大影响,基于此,从基础实验平台、泄漏流淌基底介质类型、燃烧空间环境等3个方面对流淌火室内实验研究作了介绍,并结合泄油扩散规律和燃烧特性对其数值模拟模型进行分类总结。目前针对流淌火的研究主要基于一维、二维实验平台实现,通过铺设不同基底介质和搭建各类受限空间完成对特殊环境的模拟实验,着重分析了流淌面积、燃烧面积、火焰高度、火焰前沿位置、火焰温度、烟雾特征、热辐射值及燃烧速率等对燃烧过程的影响,在一定程度上揭示了不同油品的流淌火燃烧规律与机制。多孔介质环境下流淌火的扩散与燃烧机理更为复杂,是未来流淌火研究的重要方向。Flowing fire disaster will have a huge impact on the environment,society,and economy.Based on the disaster impact caused by convective fire,indoor experimental research was introduced from three aspects:basic experimental bench,leakage flow substrate type,and combustion space environment.Combined with numerical simulation research on oil leakage diffusion law and combustion characteristics,classification and summary were carried out.The current researches on flowing fire are mainly based on one-dimensional and two-dimensional combustion platforms.This paper has completed special environmental experimental researches by laying different substrate media and building various confined spaces,emphatically analyzes the influences of flowing area,burning area,flame height,flame front position,flame temperature,smoke characteristics,thermal radiation value and combustion rate on the burning process,and reveals the law and mechanism of flow fire combustion of different oil products to some extent.The diffusion and combustion mechanism of flow fire in porous media are more complex,which is an important research direction of flow fire in the future.
