当流动受到压缩性影响时，层流边界层中产生的戈特勒涡会经历显着的变化。在本研究中，五个 .次谐波类型可能是最危险的模式，而失谐类型可以忽略不计，尽管一些次主导的次要模式在失谐状态下达到其峰值增长率。
Görtler vortices developed in laminar boundary layer experience remarkable changes when the flow is subjected to compressibility effects. In the present study, five . The subharmonic type can be the most dangerous mode while the detuned type can be neglected, although some of the sub-dominant secondary modes reach their peak growth rates under detuned states.
