这项工作的目的是用光学方法证明在高超声速平面边界层中非侵入性激发任意频率和幅度的第二模不稳定波的可能性。利用表面热流传感器测量了平板上自然和人工激发的零攻角不稳定波。这些测量是使用同花顺安装的高频热流传感器的串流阵列进行的。此外,表面压力传感器的应用也显示了不稳定波。显示了通过局部加热模型表面来产生这种波的可能性。
The aim of this work is to show the possibility of non-intrusively exciting second-mode instability waves with arbitrary frequency and amplitude in a hypersonic, planar boundary layer, by means of optical methods. Surface heat flux sensors were used to measure natural and artificially excited instability waves on a flat plate at zero angle of attack. The measurements were made using a stream-wise array of flush-mounted high-frequency heat flux sensors. In addition, surface pressure sensors were applied and show the instability waves, as well. The possibility to generate such waves by locally heating the model surface is shown.
