摘　　要：为研究一种新型炮口装置对火炮发射时膛口流场的影响,文中运用计算流体力学相关知识,采用包含动网格的膛口流场的二维非定常粘性可压缩N-S方程组进行模拟仿真。分析了在有无该装置的两种情况下,炮口流场的激波系结构形成与发展的过程。结果表明该新型膛口装置对弹丸出炮口后运动状态影响较小,炮口冲击波满足对环境及人员的要求。To research the influence of a new muzzle attachment in muzzle flow field when gun launch,the computational fluid dynamics and dynamic mesh techniques and two-dimensional unsteady viscous compressible N-S equations were used to simulate in muzzle flow field.The shock structure conformation and development of the process in the muzzle flow field were analyzed when the device is available /unavailable.The results show that the influence by muzzle flow field on the state motion of the projectile is little,and the blast impact of this muzzle attachment on the environment and personnel meets the requirements
