膛口冲击波的远场传播规律

The Propagating Laws of Muzzle Blast Far Away from the Gun

本文利用高阶精度妁Godunov格式,数值模拟了膛口冲击波在远场的传播过程.计算结果显示膛口冲击波的动球心球形波特征,以及冲击波超压在传播过程中的指数衰减规律.

In this paper,the propagating process of muzzle blast far away from the gunis numerically simulated with the help of hign order Gofunov scheme.The results of cal-culation show the properties of spherical blast wave with varying strength and movingspherical center and the exponential decaying laws of blast overpressure in propagatingprocess
