of a regular, periodically alternating Karman vortex street.
However, little attention has been paid to the effect of an
adjacent free surface on the development of the Karman
vortices and possible generation of new classes of the nearwake
structure[1], see Figure 1. The technique of Particle
Image Velocimetry (PIV) is a useful tool to this flow,
considering that it is unsteady and multi-scale in nature.详细>
