摘要:
使用红外热成像仪记录了TNT和温压炸药爆炸后的火球表面温度场，得到了2种炸药的爆炸火球表面最高温度、持续时间、火球尺寸和火球温度变化速率等参数，并对温压炸药后燃烧对火球温度的影响进行了分析。结果表明，温压炸药爆炸火球的不同时刻最高温度和持续时间都大于TNT，温压炸药火球体积较大，且更为扁平，温压炸药和TNT爆炸火球的温度变化速率曲线分别呈“V”和“L”型，强烈的后燃烧使得温压炸药爆炸火球温度衰减较慢,持续时间较长。
Abstract:
Surface temperatures of TNTs and thermobaric explosives fireball were measured by the infrared thermal imager respectively. Some parameters of the two fireballs, including highest surface temperature, the duration at certain temperature, the size of the fireballs and the rate of temperature change, were observed. Moreover, the influence of post burning on the temperature of fireball was also analyzed. Results show that the fireball of thermobaric explosive always has higher temperature and longer duration of high temperature than those of TNT. In addition, the fireball of the thermobaric explosive is bigger and flatter. The temperature changing curves of fireballs of thermobaric explosive and TNT are in “V” and “L” shapes, respectively. Strong post burning makes the fireball of the thermobaric explosive has slower temperature damping and longer duration contrasted with those of TNT.
