The Characteristics of Aeolian Tone Generated from Elliptic and Rectangular Cylinders

Abstract

The characteristics of the Aeolian tone generated from elliptic and rectangular cylinder with cross sectional aspect ratio of 1 to 4 are studied experimentally. The characteristics of the Aeolian tone from elliptic cylinders are affected by relatively small change of the Reynolds number. The aspect ratio shows some critical value for the occurrence of the reattachment of the flow to the side surface
