摘要
本文应用膛内反应两相流动的数学物理模型,采用在药室中设置有质量、动量、能量交换的中心点火管,发射装药,弹与膛壁间隙区等多排平行一维网格的摸拟方法,分析了药包装药结构下的大口径火炮膛内压力波的形成过程,讨论了影响压力波形成与发展的各种因素。
This paper used the mathematical and physical model of the two-phase reacting flow within the bore and the simulative method of parallel one-dimensional meshes with many rows (the center-core igniter, the propellant change and the gap bet ween the projectile and charmber wall) in which mass, momentum and energy change were installed. This paper also analyses the process of the formation and development in the pressure wave within the bore of large-caliber guns the construction of bag charge and discussed various factors which effected the formation and development of the pressure waves.
