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 ,两相流动状态比单相气体流动状态更接近于实际情况
Abstract:
Based on the simplified tw o-fluid model under the assumpt ion of dilute gas-part-i cle suspensions, the complex tw o-phase f low by projectile base f low ing from ax isymmetrical in base bleed projectile has been invest igated by using high accuracy and high resolut ion schemes. T he basic features of the now-equilibrium two-phase f low which are dif ferent from part icle density that affect s base drag reduction be changed. Compared experiment, That is bet ter than one-gas flow about g as-part icle.
