Aeolian tones in wind tunnels
Keywords:Acoustic noise, Automobile cooling systems, Automobile engines, Wind tunnels, Aeolian tones, Aero-acoustic wind tunnel
AbstractTwo mechanisms that produce strong noise levels within the circuit and thereby increase the test section noise levels are illustrated with examples from a climatic wind tunnel and an aero-acoustic wind tunnel. Both of the example wind tunnels have been provided with extensive acoustic treatment to reduce background noise levels. These two mechanisms for the production of Aeolian tones can be important for any wind tunnel.
