| 摘 要： | 风洞侧壁干扰是影响风洞实验数据准确度的一个重要因素,洞壁边界层的存在会使二维翼型升力线斜率的测量值下降,在风洞设计和实验中采用多种方法来减小其干扰。简述了减小或消除侧壁干扰的实验原理、实验方法、优缺点及国内外研究进展,重点介绍了侧壁抽吸、侧壁吹除控制与修正方法,最后介绍了判断控制和修正效果的准则。侧壁抽吸与侧壁吹除方法在实际应用中取得了良好的效果,对抑制侧壁边界层效应有一定作用,能够提高实验结果的精确性。

| Abstract: | The interference on wind tunnel sidewall is a key factor which affects the accuracy of wind tunnel experiment data.The existence of sidewall boundary layer will decrease the measure value of 2-D airfoil's lift line slope.There are many measures to decrease the interference in wind tunnel design and test.It describes methods of control and correction which can diminish or eliminate the interference of wind tunnel wall,including experiment principle,experiment means,advantages & disadvantages and research dev... |
