摘　　要：建立大口径火炮发射时膛口流场的二维数值模拟模型,通过耦合大位移变形的动边界及非结构动网格技术,求解可压缩流动的N-S方程,分析了炮口流场的激波系结构与发展过程,得到了由膛口冲击波及其包围着的射流结构所组成的膛口全流场的流动参数和分布图。The two-dimensional model of the muzzle flow field for numerical simulation was set up in the paper.By coupling the moving boundary of a large displacement deformation and non-structural dynamic mesh,the N-S equation of compressible flow was solved,the muzzle flow field structure and the development process were analyzed,and the parameters and distribution of the muzzle flow field consisting of the muzzle blast and the surrounding jet structure were obtained.
