| 摘要: |
| 利用高速摄影仪和纹影仪，对超声速流中两凹腔火焰稳定器交错布置的流场结构进行了实验研究。结果表明，凹腔间相互作用主要体现为激波的相互作用，两凹腔间波系相互作用，使各自流场结构发生变化；两相同短凹腔或长凹腔交错布置，凹腔各自波系增强；短凹腔和长凹腔交错布置，各自波系都减弱。 |

| Abstract: |
| Interaction between two interleaved installation cavities in supersonic flow was experimentally investigated with high speed camera and schlieren system. Results revealed that shock interaction was main affection between two cavities, shock interaction between two cavities lead to the change of cavities flowfield；double cavities with same length range(short or long) will strengthen the compression shock or expansion shock; different length cavities combine will decrease the flow strength. |
