The work is devoted to the study of a vortex system formed in a flow past a streamwise-aligned external dihedral corner due to the drop of pressure between the corner faces. A detailed comparison of experimental and calculated data on the visualization of the flow and on the distribution of pressure over the model surface obtained at Mach number M_∞ = 2.27 in the range of angles of attack α = 0–20° is reported.

超音速流中外二面角上失速涡流的演变

该工作致力于研究由于角面之间的压力下降而经过流向对齐的外部二面角的流动中形成的涡流系统。据报道，在攻角α = 0-20°范围内，以马赫数_M∞ = 2.27获得的关于流动的可视化和模型表面上压力分布的实验数据和计算数据的详细比较。
