高超声速边界层感受性是边界层转捩预测与控制的关键环节,其对高超声速飞行器研究至关重要。目前关于高超声速边界层感受性的实验研究仍然十分匮乏,为了更好地理解高超声速边界层感受性过程并指导该领域的实验研究,文章梳理了近20年来国际上高超声速边界层感受性问题的研究内容,包括对自由流扰动和壁面扰动的感受性,并主要介绍了Fedorov的前缘感受性理论和模态转化机制。最后总结了自由流扰动中感受性的不同发展路径。
Hypersonic boundary layer sensitivity is the key link in the prediction and control of boundary layer transition, which is very important for hypersonic vehicle research. At present, the experimental research on the hypersonic boundary layer sensitivity is still scarce. In order to better understand the process of the hypersonic boundary layer sensitivity and guide the experimental research in this field, the article reviews the research content of the international hypersonic boundary layer sensitivity in recent 20 years , Including the sensitivity to free-flow disturbance and wall disturbance, and mainly introduces Fedorov’s frontal receptivity theory and modal transformation mechanism. Finally, the author summarizes the different development paths of sensibility in the disturbance of free flow.
