抜粋

A control of periodic vortex shedding behind a cylindrical bluff body has been made experimentally by vibrating side-plates with piezoelectric actuators. Entrainment of the vortex shedding frequency occurs by the vibration with amplitude of 20≈65 μm. The entrainment effect is evaluated quantitatively by introducing an integral scale of the frequency in the power spectral density distribution. When the side-plates are vibrated with an opposite phase in a half span of the body, the vortex shedding follows up the vibration. In the mid span, a switching phenomenon of the vortex shedding is observed.
