摘　　要：本研究采用MATLAB和FLUENT软件对多种直流低速风洞的收缩段曲线进行仿真研究,通过对仿真结果及建模进行分析,为直流低速风洞收缩段的设计寻找出一种较为合适的曲线。对维氏曲线、双三次曲线和五次方曲线的对比图进行分析后得出,当收缩段曲线采用双三次曲线时,收缩段出入口较为平滑,且加速部分位于收缩段内部,从而使其收敛性质比其他曲线更优秀,笔者对直流低速风洞的收缩段曲线进行仿真研究,为如何设计与构建出优秀的低速风洞提供重要依据。In this study,MATLAB and FLUENT software were used to simulate the contraction section curves of various DC low-speed wind tunnels.By analyzing the simulation results and modeling,a more suitable curve was found for the design of the contraction section of the DC low-speed wind tunnel.After analyzing the contrast figure of vickers curve,bicubic curve and quintic curve,it is concluded that when the contraction section curve adopts bicubic curve,the entrance and exit of contraction section are smooth,and the acceleration part is located inside the contraction section,so that its convergence property is better than other curves.The author makes a simulation study on the contraction section curve of DC low-speed wind tunnel,which provides an important basis for how to design and construct an excellent low-speed wind tunnel.
