本文对固体火箭发动机点火过程的内流场进行了二维无粘非定常分析,计算得到了该阶段燃烧室中压强、温度和速度的分布。本文还提出了用以近似预示复杂三维装药发动机内流场的有效容积法。
In this paper, the unsteady two-dimensional viscous flow in the solid rocket motor is analyzed, and the distribution of pressure, temperature and velocity in the combustion chamber is calculated. This paper also proposed an effective volumetric method to approximate the flow field in a complex three-dimensional charged engine.
