Passive noise control by enhancing aeroacoustic interference due to structural discontinuities in close proximity (2011)
Journal Article
Leung, R. C., So, R. M., Tang, S. K., & Wang, X. Q. (2011). Passive noise control by enhancing aeroacoustic interference due to structural discontinuities in close proximity. Journal of Sound and Vibration, 330(14), 3316-3333. https://doi.org/10.1016/j.jsv.2011.02.011

In-duct devices are commonly installed in flow ducts for various flow management purposes. The structural construction of these devices indispensably creates disruption to smooth flow through duct passages so they exist as structural discontinuities...
