Görtler instability studies are conducted considering a more realistic geometry represented by the pressure side of a turbine blade. The creation and maintenance of Görtler vortices are observed in regions where the centrifugal effect exists but decays. The weak aspect of the instability leads to the selection of the preferred wave number to a receptivity problem. Shear and heat studies show transfer rates higher than the ones observed in a fully turbulent regime.

涡轮叶片上的Görtler不稳定性

进行戈特勒不稳定性研究时，考虑了涡轮叶片压力侧所代表的更逼真的几何形状。在存在离心效应但衰减的区域中观察到了Görtler涡流的产生和维持。不稳定性的弱点导致选择首选波数会引起接收问题。剪切和加热研究表明，传热速率高于在完全湍流状态下观察到的传热速率。
