Abstract
A series of experiments over a Reynolds-number range of 2.2×104-6.3×104 was conducted to understand the effect of acoustic excitation on the vortex-induced vibration of a circular cylinder. The frequency and the intensity of the applied sound were varied The following results are obtained: (1) The most effective frequency of the acoustic excitation in suppressing the vortex-induced vibration approximately corresponds to the frequency of transition waves in shear layers separated from the cylinder surface; (2) Although the applied sound is less effective in reducing a large vortex-induced vibration amplitude, the applied sound with stronger intensity can suppress the vibration more effectively.
