摘要: 采用CE/SE方法数值模拟悬浮在空气中的RDX炸药粉尘的两相爆轰过程.炸药颗粒在爆轰波阵面后的高温高速气流中加速并升温,释放能量支持爆轰波传播.数值模拟爆轰波管中的粉尘爆轰,得到爆轰波流场中的物理量分布,确定爆轰参数,数值结果与文献符合较好.数值模拟复杂通道中的炸药粉尘爆轰,预测了爆轰波的发展和传播过程以及爆轰波后的流场演化.数值结果表明CE/SE方法能成功模拟气体-固体两相爆轰,为粉尘爆轰的研究提供了新的数值预测手段.

Abstract: Two-phase detonation of RDX particles suspended in air was numerically studied with CE/SE method.Behind leading shock front of detonation,explosive particles are accelerated and heated by the gas flow.Energy is released to support propagation of detonation wave.Dust detonation in a shock tube was numerically simulated.Distribution of physical quantity behind leading shock front was calculated.Parameters of detonation were obtained and they agree well with those in a reference.Dust detonation in a complex channel was numerically simulated.It shows that CE/SE method simulates gas-solid two-phase detonation successfully.

Key words: CE/SE, two-phase detonation, explosive dust, numerical simulation
