摘要: 在隧道环境中,流淌火的火焰分叉融合、振荡和倾斜等燃烧行为,扩散油层的流动及其与隧道底壁面、火焰烟气的热传递过程具有复杂性和非稳定性。这会加剧引燃周围其他可燃物的危险性,给人们的生命财产安全带来严重威胁。通过对开放空间与隧道环境中溢油流淌火的扩散与燃烧行为、火焰高度、火焰振荡、火焰热辐射模型、热传递机制、烟气蔓延过程以及顶棚温升模型等的对比分析,指出未来应该进一步深入研究流淌火火焰振荡以及火焰热辐射模型等火焰行为,揭示流淌火蔓延的热传递机制、非稳态燃烧和烟气蔓延动力学规律,为隧道流淌火的防治和应急救援提供理论和技术支持。

Abstract: In the tunnel environment, the combustion dynamics of spill fires, encompassing phenomena such as flame bifurcation fusion, oscillations, and tilting, coupled with the fluidic behavior of diffused fuel layers and heat transfer interactions with the tunnel's bottom wall and flame smoke, exhibit significant complexity and instability. These complexities heighten the risk of igniting neighboring combustible materials, posing significant threats to human life and property safety. The present study delves into a comparative analysis of the diffusion, combustion characteristics, flame height, oscillations, heat radiation models, heat transfer mechanisms, smoke dissemination, and ceiling temperature escalation models of oil spill fires in both open spaces and tunnel environments. Notably, it highlights the need for further research to refine our understanding of flame oscillations, heat radiation models, and other flame behavioral patterns. By elucidating the heat transfer mechanisms, unsteady combustion dynamics, and smoke dispersal dynamics of spill fires, this work provides vital theoretical and technological underpinnings for the prevention and emergency response strategies against tunnel flow fires.
