已经在多个雷诺数范围内的翼型上观察到近失速时翼型的低频流动振荡。然而，振荡所涉及的长时间尺度的选择机制仍然远未明确。这为继续研究该主题提供了动力。在这里，我们努力进一步记录该现象的特征，并进一步了解流动机制。
The low-frequency flow oscillation on airfoils near stall has been observed on several airfoils over a range of Reynolds numbers. However, the mechanism of selection of the long time scale involved in the oscillation remained far from clearly understood. This provided motivation to continue to pursue the topic. Here, efforts are made to further document the characteristics of the phenomenon and gain additional insight into the flow mechanisms.
