摘　　要：为详细了解新型模块装药火炮膛内发射过程中各模块区及中心可燃管区着火、燃烧现象以及压力波动情况，建立了准二维两相流内弹道燃烧理论模型。模拟结果表明，膛底与膛口压力、压力差数值计算结果与实验结果吻合得很好。The quasi two dimensional two phase flow interior ballistic model with combustion is established,which allows to take into account explicitly the ignition and combustion phenomena of each container and centercore igniter as well as the pressure wave in the gun.The computed results of pressure and pressure difference are quite in agreement with the experimental at the breech and chamber mouth.
