| 摘 要： | 采用STAR-CD计算流体软件对某俄式发动机的喷管内流场及喷管出口处流场进行了三维的数值仿真与研究。分析了喷管内流场及喷管出口处流场的流动情况和设置不同出口边界位置对喷管中流场分离点及斜激波反射点的位置的影响,得到了清晰的流场压力与马赫数的分布云图与曲线图。仿真结果与地面热试车试验测得的结果相吻合。可为固体火箭发动机喷管的设计与研究提供有效参考。

| Abstract: | Numerical 3D simulation and research on inner nozzle and outlet flow field of solid rocket motor of long range missile designed by Russia using STAR-CD computational fluid software. Analyze the flow condition of inner nozzle and outlet flow field, analyze the influence on the position of separation point and oblique shock reflection point by setting different position of pressure boundary condition, obtain the clear distribution of contour and curve figures of flow field pressure and mach number. The simulation results are very similar to that of ground experiments. Good references for solid rocket motor nozzle design and research are provided. |
