Abstract
The Aeolian tone generated from two-dimensional objects has been widely studied by many researchers. In this study, the Aeolian tone and the related flow fields of three types of tapered cylinders are measured and are compared with those of straight cylinders. It is found that the level of the Aeolian tone decreases with the taper ratio. For the cylinder of smaller taper ratio, different peaks in the velocity fluctuation appear in blocks along spanwise location, corresponding to different peaks in Aeolian tone spectrum. The wake for higher taper ratio cylinder does not show the Karman vortex shedding and peaks of the Aeolian tone is not found.
