摘要本文在了解含铝炸药这一课题研究背景及现状的情况下,对现有研究存在的问题或不足进行了说明,熟悉了两相爆轰理论知识,对两相爆轰模型有了初步的了解,并对两相爆轰的数值计算有了一个初步的掌握。介绍了四种反应模型,分别是ZND模型、基元反应模型、二步反应模型、Sichel二步反应模型,并在ZND模型—悬浮RDX粉尘爆轰问题的研究中,解决了一个小问题—当RDX达到熔点温度时,忽略能量损失,利用热传导公式,对气相温度进行了求解。对基元反应模型进行了修正,以往比热比总是作为常数,这里引入了变化的比热比,并对Arrhenius定律进行了修正。介绍了导爆管的一些传爆特性,对其传爆性能参数进行了定量分析,并对传爆参数进行设计与计算。63635

Title The calculations of RDX mixed with aluminum-containing dust stable booster detonation wave structure .
Abstract Based on the understanding of aluminized explosives research background and current situation of this case, study on the existing problems or deficiencies are described, familiar with the two-phase detonation theory knowledge and two-phase detonation model, and the numerical calculation of two-phase detonation has made a preliminary grasp. Describes four reaction model, namely ZND model reaction model, two-step reaction model, Sichel two-step reaction model, and in the ZND model – the dust of RDX suspended detonation problems of the study, to solve a small problem - when RDX reach the melting point temperature, the energy loss is ignored, by heat conduction equation is solved for the gas temperature. On the chemical reaction model was modified in the past as a constant specific heat ratio is always here to introduce a change in the specific heat ratio, and Arrhenius's law was amended. Introduced detonating booster features some of its booster performance parameters were quantitatively analyzed, and the booster design and calculation parameters.
