摘要
基于内弹道两相流模型,考虑到点火药量与主装药相当及其固体燃烧产物所占比例大等影响,提出了适用于电爆管内燃烧过程的内弹道“四相流”模型,即将气态燃烧产物、固态燃烧产物、点火药和主装药分别作为一“相”参与燃烧和流动,每一“相”都用质量、动量和能量方程描述,而它们之间的各种相互作用以源项的形式出现在上述方程中。模型计算结果与电爆管实验结果一致,表明该模型对于电爆管内燃烧过程的描述是合理的,可以作为分析该电爆管燃烧性能的一种辅助工具。
Based on two phase flow model of interior ballistics, considered that the weight of ignition charge is comparable with the secondery charge and many of its products are solid,the so called four phase flow model of interior ballistics adaptive to the combustion process in the electric squib has been established. In the model, gas products, solid products, ignition charge and secondery chare, all be taken as a phase,each of them is described by mass,momentum and energy equation,and they are related by mutual actions,which are the source terms in the before-mentioned equations. Caculated result by the model is in agreement with the test of the electric squib. This shows that the model describes reasonably the combustion process in the electric squib, and can be as an assistant tool for evaluating of the performance of electric squib.
