摘要

摘要在本文中，我们介绍了对具有薄抛物线轮廓的非后掠翼上的超音速边界层易受不同强度声学噪声影响的过程进行直接数值建模的结果。结果表明，声学噪声可导致超音速客机无后掠面机翼上的层流-湍流过渡。

Transition of a Supersonic Boundary Layer Over an Unswept Wing Due to Acoustic Noise

In this paper, we present the results of direct numerical modeling of the process of susceptibility of a supersonic boundary layer over an unswept wing with a thin parabolic profile to acoustic noise of various intensities. It was demonstrated that acoustic noise can cause a laminar–turbulent transition over the unswept wing of a supersonic passenger aircraft.
