Flow Induced Noise
The focus of the Flow-Induced Noise Technical Group is the basic understanding and control of acoustic noise and structural vibration generated by fluid flow. The engineering challenges cover a very wide range of fluid/acoustic phenomena involving atmospheric acoustic media and the noise created by compressible fluid flow, as well as liquid acoustic media and the associated noise and vibration generated by essentially incompressible flows. Progress in developing models and supporting experimental data bases permits the description of possible noise control methods that can be evaluated analytically or numerically, and then with confidence, prototype apparati may be evaluated in the laboratory.
