摘　　要：介绍的五次曲线收缩段壁型是一种新型风洞壁型，与通常采用的壁型相比，具有边界层厚度薄，流场湍流度低，气流均匀性好等综合效果。该收缩段壁型有推广价值。Characteristics of the five-order curve wall shape in the tapering section of wind tunnel is a new design introduced in this paper. Compared with other walls of normal design, it has a thinner boundary layer and lower turbulence for the flow field,this wall of tapering section extends beneficially to other tunnels.
