开展了小尺度环形油池火实验,测量了燃料的质量损失速率,记录了火焰形态的变化,借助编制的图像分析程序处理实验视频,得到了环形油池火的连续火焰高度和最大火焰高度。将Hasemi羽流中心线温度模型的理论值与实验值进行了对比,得出相应结论。根据实验结果提出了环形油池火灭火救援应当注意的事项。
A small-scale annular oil pool fire experiment was carried out. The mass loss rate of the fuel was measured and the change of the flame shape was recorded. The experimental video was processed by the programmed image analysis program to obtain the continuous flame height and the maximum flame height of the annular oil pool fire. The theoretical and experimental values of Hasemi plume centerline temperature model are compared and the corresponding conclusions are drawn. According to the experimental results, it is necessary to pay attention to the annular oil pool fire fighting and rescue.
