不同气体环境对液固混合FAE爆炸能量的影响研究

为了研究不同气体环境对液固混合FAE爆炸能量的影响,利用爆热量热计和密闭爆炸容器,分别在真空、空气和纯氧三种条件下,测定了液固混合FAE的爆热和准静态压力。结果表明：爆热和准静态压力的大小符合如下顺序：纯氧＞空气＞真空,即随着环境中氧气含量的增加,试样的氧化完全性更高,且释放出更多的能量；同时,通过对试验数据进行分析,拟合得到了准静态压力与试样爆炸释放能量的关系,即：试样的能量与准静态压力近似呈现线性关系,并满足 的关系式。

Influence of different gas environment on explosion energy of liquid-solid FAE mixture

In order to investigate influence of different gas environment on explosion energy of liquid-solid FAE mixture, the detonation heat calorimeter and closed explosion system were developed respectively. The detonation heat and quasi-static pressure were measured under three conditions, vacuum, air and pure oxygen. Results show that the sequence of detonation heat and quasi-static pressure under the three conditions is: pure oxygen>air>vacuum. The results indicate that with the increasing of the oxygen content, the oxidability of FAE increased gradually, and release more energy. The relationship between quasi-static pressure and released energy of FAE was also obtained. The fitting result demonstrates that the released energy and quasi-static pressure approximately follows linear relationship: .
