片状随行装药的两相流数值模拟

The Simulation of Disk Traveling Charge Two Phase Flow

给出了片状随行装药结构的一维两相流数学物理模型，并对某５７ｍ ｍ 随行装药火炮进行了数值模拟。研究了片状随行装药火炮的膛压、压力波、气固相速度以及空隙率等参量的分布情况。此外，还对比研究了计算结果与实验结果之间的差异。结果表明。

In this paper, the one dimension two phase flow model of disk traveling charge was established, and some simulation to one 57mmH gun were made. The distribution of pressure, pressure wave, the velocity of gas and propellant and so on were researched. The difference between the calculated and firing experimental results was compared. The results indicated that the calculated results were very similar to the experimental results.
