electric squib

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.

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。
