| 摘要: |
| 基于拼接网格系统，应用三维区域边界格式；通过区域边界格式对区域边界上的通量进行守恒性处理，发展了一个超音速复杂流场分区算法；对不同攻角下的逃逸飞行器喷流干扰流场进行了分区数值模拟，取得了较好的结果。 |

| Abstract: |
| According to the conservation of flux on the zonal boundary,a two and three dimensional zonal boundary schemes are derived for patched grid systems.Based on this work,a multizonal numerical algorithm is developed for 2D/3D viscous complicated flow field with supersonic jet.Using this algorithm,the Launch Escape Vehicle (LEV) jet interaction viscous flow field is numerically simulated with angle of attack of 4°and 8°. |
| Keywords: LEV jet flow boundary scheme multizonal numerical simulation |
