在高超声速(M=6)流动中,实验研究了侧向喷流的干扰特性,并探讨了喷流压力、攻角、迎风侧及背风侧喷流对侧向喷流干扰特性的影响.结果表明,在高超声速流动中,随喷流压力增大,喷流弓形激波与来流弓形激波相交,喷流前的高压区增大,而喷流后的低压区几乎不受影响,喷流的控制效果加强.与迎风侧喷流相比,背风侧喷流控制效果更好,这一趋势随攻角的增大更加明显. |

Experimental investigations of the lateral jet interaction have been performed in hypersonic flows (M = 6) to study the effects of jet pressures, angle of attacks, leeward side jet or windward side jet on the jet interaction characteris-tics . The results indicated that the interaction flowfields of the lateral jet in hypersonic flows included the high pressure re-gion and shock waves before the lateral jet, the low pressure region induced by the jet after the lateral jet and the wraparound effect region, these regions determined the interaction characteristics of the lateral jet. In hypersonic flow, with increasing of jet pressures, the jet bow shock intersected with the freestream bow shock, the high pressure region before lat-eral jet extended forward, but the low pressure region almost unchanged, so the jet interaction control were enhanced. In the case of angle of attacks, the high pressure region before the leeward jets enlarged, and the jet interaction control of lee-ward jet was more effective than the windward jets. |
