Suppression of vortex-induced vibration of a circular cylinder by a finite-span flexible splitter plate
Guo-Peng Cui, Li-Hao Feng
Abstract
We present experiment and analysis of the effectiveness of a flexible splitter plate in the suppression of vortex-induced vibration (VIV) of a circular cylinder. The important finding is that it is not necessary to suppress VIV by a full-span flexible splitter plate, while efficient control can be achieved by a finite-span one. The fluid-structure interaction and control mechanism are revealed by analysis of wake evolution and force characteristics.
