燃料空气炸药爆炸温度场参数实验研究

运用红外热成像仪Mikroanscan7200V分别对TNT、SEFAE和DEFAE爆炸火球的表面温度进行了测量,讨论了TNT、L-SEFAE、G-SEFAE、DEFAE炸药的温度场的分布情况.结果表明,DEFAE表面温度最高,高温（≥1000℃）持续的时间也最长;DEFAE的温度场效应要比SEFAE、TNT高;TNT、LSEFAE、G-SEFAE和DE-FAE在温度场接近最大温度时的火球平均直径为D（-）DEFAE＞D（-）G-SEFAE＞D（-）L-SEFAE＞D（-）TNT.

Experimental Study on the Parameter of FAE's Temperature Field

Using the Mikroanscan 7200V Thermal Imager, the blasting fireball＇s surface temperature of TNT, SEFAE,and DEFAE were measured. The temperature distribution of TNT, L-SEFAE, G-SEFAE and DEFAE explosives are discussed. The results show that,for the four equal-quality explosives,surface temperature,the time of high temperature （≥1000℃）and temperature field effects of the DEFAE is highest,longest and best. Approaching the highest blasting temperature,the fireball＇s average diameter iS.D^-DEFAE〉D^-G-SEFAE〉D^-L-SEFAE〉D^-TNT.
