摘　　要：风洞是空气动力学实验的基本设备,低速风洞出口实验段流场速度均匀性良好是保证气动实验正确的先决条件。本文基于CFD方法,结合风洞实验结果,对低速风洞流场进行数值模拟,比较分析两种不同洞体结构流场品质,得出改变洞体结构可以影响出口实验段流场的速度均匀性这一结论。The wind tunnel is a fundamental aerodynamics experiment＇s set,it is the precondition to guarantee aerodynamics experiment＇s accuracy that the speed uniformity on the exports section of low-speed wind tunnel is good.This article is based on the CFD method and the wind tunnel experiment＇s result,and carries on the numerical simulation for flow field of the low-speed wind tunnel,and comparatively analysis flow field quality of two kind of different wind tunnel＇s structure,Finally,We obtain the conclusion that changing wind tunnel＇s structure can affect the speed uniformity on the exports section of low-speed wind tunnel.
