在核安全研究框架内对在受限和通风防火分区内油池火燃烧速率进行了试验研究.在实体火灾试验基础上,此研究为在受限和通风火灾场景下的燃烧速率机理提供了新的信息.描述了在自由条件和空气受限条件下所进行的试验,对试验装置、仪器以及火源进行了详细叙述.在相同场景(0.4 m2 TPH 油池火)下,对自由条件和空气受限条件的试验情况下的燃烧速率进行了对比.在空气受限情况下,燃烧速率与时间的变化曲线显示出三个不同阶段:自由条件和受限燃烧速率相同;不稳定阶段,空气受限条件下燃烧速率高于自由条件下的燃烧速率;稳定阶段.从图像分析看,不稳定阶段显示,动荡和间歇火焰大大提高了燃烧速率.介绍了通风速率和油池面积对此现象的影响.试验结果为理解有限区域内燃烧速率提供了新的试验信息.
