摘要
借助于稀颗粒假定下的双流体简化模型 ,采用具有高精度、高分辨率数值方法 ,研究了轴对称底部排气弹弹底混合绕射的复杂两相流动 ,得到了非平衡两相流中颗粒相浓度大小对底排弹减阻性能影响的规律。与实验比较 。
Based on the simplified two fluid model under the assumption of dilute gas particle suspensions, the complex two phase flow by projectile base flowing from axisymmetrical in base bleed projectile has been investigated by using high accuracy and high resolution schemes. The basic features of the now equilibrium two phase flow which are different from particle density that affects base drag reduction be changed. Compared experiment, That is better than one gas flow about gas particle.
