摘要：

为研究边界层吸入（BLI，boundary layer ingestion）对 S 形进气道流场畸变的影响，本文设计了短扩压、小偏

距的 S 形进气道，分析了边界层吸入对 S 形进气道流场特性的影响，进一步研究了吸入不同厚度边界层对

出口流场的影响。结果表明，边界层吸入时，进气道内流体的三维分离流动产生对涡旋流畸变区，使低能流

体在进气道底部堆积，在出口位置形成特有的下凹形状总压畸变区。随着吸入边界层厚度的增加，进气道

流通能力下降，出口截面处总压畸变强度和范围都增大，而旋流畸变范围小幅增加，旋流强度无显著变化

Abstract:

: In order to study the effect of boundary layer ingestion (BLI) on the flow field distortion of the S-Shaped intake, a

short spread pressure and small offset S-shaped intake is designed in this paper, the effect of BLI on the flow field

characteristic of S-shaped intake is analyzed, and the effect of inhaling boundary layers of different thicknesses on

the outlet flow field is further researched. The results show that when the boundary layer is inhaling, the three-dimensional separation flow of the fluid inside the inlet forms a twin swirl distortion zone, low-energy fluid accumulated at the bottom of the intake tract, and forms a unique concave shape total pressure distortion zone at the exit

position. With the increase of the thickness of the suction boundary layer, the flow capacity of the inlet tract decreases, and the total pressure distortion intensity and range at the outlet section increase. However, the range of

swirl distortion slightly increases, and there is no significant change in swirl intensity.

Key words:

boundary layer ingestion, S-shaped intake, total pressure distortion, swirl distortion
