| 摘 要： | 在小尺寸实验中重现了火焰的旋转现象,并在没有外部鼓风的情况下,实现了旋转火焰自发产生;对室内火灾的旋转火焰现象进行了描述,得出旋转火焰具有自旋、根部变细、焰柱增长和旋转中心飘移等特征;并进一步分析了旋转与非旋转火焰各火灾参数的不同,结果表明,旋转火焰比非旋转火焰具有更大的火灾危险性。

| Abstract: | The rotating flames are reproduced in a small scale in this experiment,and the whirling flames are produced spontaneously without outer blasts.The phenomena of whirling flames in enclosure fires are described.The periodic formation,rotation,core deviation and destruction of whirling flames have been observed,and the characteristics such as the rotation,thinner root,longer flame and core deviation are obtained.The fire parameters of whirling flames and non-whirling flames are studied in this paper.The conclusion made is that the whirling flames are more dangerous than the non-whirling flames. |
