Acoustic quasi-steady response of thin walled perforated liners with bias and grazing flows

This paper considers the acoustic performance of a passive damper in which acoustic energy is absorbed by orifices located within a thin plate (i.e. a perforated liner). The perforated liner, which incorporates orifices of length to diameter ratios of ~0.2, is supplied with flow from a passage. This...
