The effects water mist has on the overpressures produced by the detonation of 50 lb equivalent of high explosives (HE) TNT and Destex in a chamber is reported. The overpressures for each charge density were measured with and without mist preemptively sprayed into the space. A droplet analyzer was placed in the chamber prior to the detonation experiments to characterize the water mist used to mitigate the explosion overpressures. The impulse, initial blast wave, and quasi-static overpressure measured in the blast mitigation experiments were reduced by as much as 40%, 36%, 35% for TNT and 43%, 25%, 33% for Destex when water mist was sprayed 60s prior to detonation at a concentration of 70 g/m(3) and droplet Sauter Mean Diameter (SMD) 54 microm. These results suggest that current water mist technology is a potentially promising concept for the mitigation of overpressure effects produced from the detonation of high explosives.
报告了水雾对在一个室内50磅当量的高爆炸药（HE）TNT和Destex爆炸产生的超压的影响。在有和没有预先向空间中喷洒水雾的情况下，测量了每种装药密度下的超压。在爆炸实验之前，将一个液滴分析仪放置在室内，以表征用于减轻爆炸超压的水雾。当在爆炸前60秒以70 g/m(3)的浓度和54微米的液滴索特平均直径（SMD）喷洒水雾时，在爆炸减轻实验中测量的冲量、初始冲击波和准静态超压，对于TNT分别降低了多达40%、36%、35%，对于Destex分别降低了43%、25%、33%。这些结果表明，当前的水雾技术对于减轻高爆炸药爆炸产生的超压影响是一个潜在的有前景的概念。
