摘要
在风洞中正确复现大气边界层流动特性，是风洞试验结果可信的必要条件．为此总结了在同济大学ＴＪ－２风洞中模拟缩尺比为１：５００的大气边界层Ａ，Ｂ，Ｃ，Ｄ等４类流场的试验研究工作，全面考虑了风速剖面、湍流度剖面、脉动风功率谱和湍流尺度４项指标，为进一步风洞试验工作提供了基础．
Correctly simulating the wind field characteristics of the atmospheric boundary layer(ABL) in wind tunnel is necessary to the reliability of the wind tunnel test results.In this paper,four categories of flow fields of the ABL with the scale of 1:500 are simulated in TJ-2 wind tunnel at Tongji University.In these flow fields,the mean velocity profiles,turbulence intensity profiles,fluctuating wind power spectra and integrate scales are discussed,which contributes to the later work.
