在含多种点火元件的分装式高装填密度坦克炮中，考虑点火管、弹丸尾杆作用建立了轴对称两维多相流数学物理模型。并对其进行数值分析，结果表明．弹底和膛底曲线与实验有较好的一致性，被膛和尾杆处的流动壅塞引起了膛内局部压力升高。
In sub-assembly type high-density tank guns with multiple ignition elements, an axisymmetric two-dimensional multiphase flow mathematical physics model was established considering the function of the ignition pipe and the tail of the projectile. And its numerical analysis, the results show. The bottom of the bomb and the bottom of the curve and the experiment has a good consistency, the breech and the tail of the flow blockage caused by pressure within the bore increased.
