| 摘要: |
| 从考虑了k-ε湍流模型和双组分气体模型的三维薄层近似 NS 方程出发, 采用高效 ENO 差分格式, 数值模拟了超音速空气外流与塞式喷管燃气形成的内外流干扰流场。部分计算结果与国外文献相比一致。在此基础上论证了应用计算流体力学开展塞式喷管研究的可行性。 |

| Abstract: |
| Interaction of plug nozzle jets with supersonic external flow was simulated numerically based on 3-D TLA NS equations with ENO scheme, then the structure of the flow field was analyzed. Calculations were performed under two-component model in which the external flow was air and the jet was fuel gas. Turbulence was taken into account with a k-ε turbulence model. The results agreed well with the reference. |
