Abstract

The aim of this study is to detect and visualise the influence of span-wise coherence on propagating sound waves emanating from a flow around circular cylinders with span-wise variations of the local radius. Synchronous particle image velocimetry (PIV) and microphone measurements are performed in a circular wind tunnel with a nozzle size of 0:4 m × 0:4 m at a maximum flow speed of U¥ = 43ms−1. The test section is surrounded by a full anechoic chamber of approximately 9 m × 9 m × 5 m.
