摘要
使用两相流模型,对管中悬浮黑索金(RDX)粉尘混合空气的爆轰过程进行了理论分析。粉尘的爆轰波模型是以两相流模型为基准,气体和颗粒具有不同的速度及温度。本实验就RDX粉尘浓度对点火延迟、爆轰波压力、温度的影响进行了研究,得到了爆轰波中各物理量分布,并确定了RDX粉尘爆轰的浓度极限。
RDX dust detonation in suspension behind shock waves was analyzed with two-phase flow model. In the two-phase flow model,steady-state detonation regimes were studied on the basis of the mathematical model of detonation of RDX particles taking into account differences in velocities and temperatures of the mixture components. In this paper,pressure of detonation and development of temperature were numerically simulated when concentration of particle changed. Distribution of parameter was obtained and detonation of RDX dust-air in suspension didn′t arise if the concentration of particles was less than (0.076 kg·m^(-3).)
