摘要：

The formation length of Karman vortices can be drastically reduced by small-amplitude excitation at a frequency much higher than the natural frequency of Karman vortex formation, namely the Kelvin-Helmholtz (KH) frequency of the separating shear layer. Phase-locked patterns of KH vortices are attainable. These spatially stationary patterns coexist, however, with the spatial and temporal development of the Karman vortices.
