In order to evaluate the influence of shock wave formed by the explosion of cold shock extinguishing bomb on the extinguishing effect, shock wave formed by explosion dispersion of different extinguishing mediums was observed by schlieren experiment apparatus. The propagation law of shock on the interface between air and fluid was studied by numerical simulation, and finally the process of pool fire suppression by cold shock extinguishing system was photographed by high speed photography. Comparative analysis to the percent of high color stage at the same position of each image were made. It was found that the shock wave was formed after extinguishing medium dispersion, but its strength is weak. The mach reflection in the air and disturbance on the liquid surface were found when the shock wave propagated through interface of air and liquid, the strength of shock gradually attenuated with the increase of distance. The percent of high color stage in the earlier stage was weaker than in the later. So the influence of shock wave on the extinguishing effect was weaker than medium dispersion in cold shock extinguishing system.

为了研究冷激波灭火弹爆炸后形成的激波对扑灭油盆火焰的影响,首先采用纹影实验装置,观察小尺寸下不同灭火介质爆炸抛洒后的激波现象和激波强度;然后采用数值模拟的方法,模拟弱激波在气/液界面处的传播情况;最后采用高速摄影机拍摄冷激波灭火系统扑灭油盆火的实验过程,并对比分析各张图片同等位置处高色阶随时间的变化情况。通过实验发现,灭火介质爆炸抛洒后能形成激波,但激波强度较弱;当弱激波通过气/液界面时,液面上方会形成马赫反射,液面出现扰动,激波强度随距离的增加而不断衰减;前期高色阶百分比的变化弱于后期色阶百分比的变化。因此在比药量较小的冷激波灭火系统中,激波对扑灭油盆火焰的影响弱于介质抛洒。

为了研究冷激波灭火弹爆炸后形成的激波对扑灭油盆火焰的影响,首先采用纹影实验装置,观察小尺寸下不同灭火介质爆炸抛洒后的激波现象和激波强度;然后采用数值模拟的方法,模拟弱激波在气/液界面处的传播情况;最后采用高速摄影机拍摄冷激波灭火系统扑灭油盆火的实验过程,并对比分析各张图片同等位置处高色阶随时间的变化情况。通过实验发现,灭火介质爆炸抛洒后能形成激波,但激波强度较弱;当弱激波通过气/液界面时,液面上方会形成马赫反射,液面出现扰动,激波强度随距离的增加而不断衰减;前期高色阶百分比的变化弱于后期色阶百分比的变化。因此在比药量较小的冷激波灭火系统中,激波对扑灭油盆火焰的影响弱于介质抛洒。

In order to evaluate the influence of shock wave formed by the explosion of cold shock extinguishing bomb on the extinguishing effect, shock wave formed by explosion dispersion of different extinguishing mediums was observed by schlieren experiment apparatus. The propagation law of shock on the interface between air and fluid was studied by numerical simulation, and finally the process of pool fire suppression by cold shock extinguishing system was photographed by high speed photography. Comparative analysis to the percent of high color stage at the same position of each image were made. It was found that the shock wave was formed after extinguishing medium dispersion, but its strength is weak. The mach reflection in the air and disturbance on the liquid surface were found when the shock wave propagated through interface of air and liquid, the strength of shock gradually attenuated with the increase of distance. The percent of high color stage in the earlier stage was weaker than in the later. So the influence of shock wave on the extinguishing effect was weaker than medium dispersion in cold shock extinguishing system.
