粘结式随行装药两相流内弹道模型及其计算

采用将随行装药区看成是一个独立的燃烧区，主装药区与随行装药存在着质量，动量和能量的交换，从而建立了应用于粘结式随行装药结构的一维两相流内弹道模型，并论述了差分格式和边界的处理方法，给出了针对３０ｍｍ火炮随行装药结构的内弹道计算结果。

INTERBALLISTIC SIMULATION AND COMPUTATION OF TWO PHASE FLOW OF TRAVELLING CHARGE

In the course of interior ballistic, travelling charge zone can be regarded as a self governed burning zone, which can exchange mass, momentum and energy with the main charge burning zone. In this paper, work in the mechanic force travelling charge techniques were theoretically completed as follows, established the one dimension two phase flow model of interior ballistic, discussed the difference equations and the treatment of the burning zone borderline, simulated the results of the part travelling charge configuration on 30 mm gun.
