摘要:
为研究铝粉在固相炸药爆轰中的点火机理，通过建立数值仿真模型，考察了微米铝粉在TNT爆轰压力作用下的响应过程。计算结果显示，在爆轰压力作用下，铝粉颗粒会发生急速的压缩。颗粒的氧化层会在压缩过程中快速破裂，且氧化层的破裂耗时较短，有可能使铝粉在爆轰反应区内发生点火。同时，压缩还会造成颗粒内部温度的突然升高和迅速回落，但该过程对氧化层破裂所起的作用非常有限。
Abstract:
In order to clarify the ignition mechanism of Al particles in the detonation of solid explosives, the response of micro Al particles under pressure of TNT detonation was studied by numerical simulations. The calculation results show that Al particle is compressed rapidly under detonation wave pressure. The rupture of oxide shell was caused by compression so fast that the aluminum particles will be ignited in detonation reaction zone. Meanwhile, the internal temperature of aluminum particle will suddenly increase and fall back during the compression process, but this phenomenon is not dominant for oxide shell rupture.
