Abstract

The article considers the development of a near-wall separation vortex arising at a supersonic flow around the external dihedral corner due to the pressure drop between its faces, in the range of angles of attack α = 0.5°–6°. The processes of the origin and development of separation and secondary vortices at the angle increase are investigated in detail. Particular attention is paid to the flow structure change in the vortex location zone. A clear violation of the flow self-similarity in the front part of the model in the zone of vortex system formation is shown.

在 M∞ = 2.27 和 α ≤ 6° 的二面角构型附近形成分离漩涡

文章研究了在攻角 α = 0.5°-6° 的范围内，外斜角周围的超音速气流由于其表面之间的压力降而产生的近壁分离涡的发展过程。详细研究了角度增大时分离涡和次级涡的起源和发展过程。特别关注了涡旋定位区的流动结构变化。结果表明，在涡旋系统形成区，模型前部的流动自相似性明显受到破坏。
