摘要: |
绕弹体的超声速气流与火箭发动机燃气喷流相互作用,在弹底部形成了复杂的干扰流场。应用四阶的MUSCLTVD格式,求解雷诺平均的N-S方程,对这一复杂流动进行了数值模拟,得到了流场结构随不同喷口压力比的变化规律。 |

Abstract: |
The interaction between supersonic external flow and an exhaust jet forms a complex flowfield near the missile afterbody.The research about this interaction flows was completed with fourth order MUSCL TVD scheme to solve the Reynolds averaged N S equations.The flowfield structures observed and it’s relation with jet pressure ratio were obtained. |
