风洞收缩段曲线气动性能研究

介绍了一种新的风洞收缩段曲线的设计方法，即UG参数化收缩段壁型曲线设计。采用商用软件fluent对这种收缩段曲线性能进行数值模拟计算，获得了好的流场品质，对于风洞的设计以及流动优化提供了新的设计思想。在模拟计算的基础上应用了该研究成果加工制造了一座低速风洞，并对风洞流场进行了校测，对比了模拟计算结果与实验测量结果，并进行了流场性能分析。该设计方法可以应用推广到风洞设计工作中去。

Study of the performance of contractive curve for the wind tunnel

Design method of a new contractive curve for the wind tunnel contractive segment is introduced in this paper, namely the design of contractive curve of the parameter based on UG. The performance of con- tractive curve was simulated by Fluent. Favorable flow field quality is attained. A new design idea for design of the wind tunnel and flow optimize is offered. A low-speed wind tunnel with this contractive curve was made, and the flow field of this wind tunnel was measured. Contrast of the simulation result and experiment result, and the analysis of the performance of the flow field were made. The design idea can be used to other wind tunnel design.
