抄録

The vortex shedding behind a circular cylinder is one of the important issues in engineering mechanics, because the vibration induced by the vortex shedding, can cause a serious accident. In order to suppress it, the present study aims to control the vortex shedding from the cylinder. In this paper, the spherical rings were attached on the cylinder, and the streamwise and transverse velocities in the cylinder wake and the static pressure on the surface of the cylinder were measured by the hot-wire anemometer and the pressure transducer at Re_d ≈ 15,000. Also, to investigate the flow structure in the wake, the phase-averaged velocity was calculated by the conditional sampling method. As a result, it was found that the flow behavior is affected by the spanwise pitch of the spherical rings.
