The response characteristics and suppression of flow-induced vibrations of rectangular prisms with various width-to-height ratios were experimentally investigated. The present study focused on rotary oscillation, which is one of flow-induced vibrations generated in a rectangular prism. In this paper, the response characteristics on elastically supported prisms were first examined in detail by free-vibration test. Next, flow-induced vibrations obtained by the free-vibration test were reproduced by forced-vibration test, and then the generation mechanism of flow-induced vibrations was examined on the basis of the visualized flow patterns, fluctuating pressure distributions of the surface of prism and characteristics of flow-induced vibrations by the flow control.
