摘要：

The paper explores the application of the inviscid instability approach to externally excited turbulent free shear flows at high Reynolds numbers. After qualitative descriptions of coherent structures, the following topics are covered: application of the linear stability theory to large coherent structures in free turbulent shear flows; nonlinear evolution of instabilities in free shear flows; the 'preferred mode' concept; and vortex pairing in turbulent mixing layers. Finally, experimental results concerning control of free turbulent shear layers are presented.
