RISParticle Image Velocimetry Measurements of Aeroacoustic Sources of a Shallow Cavity in a Pipeline
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: ) (Mohamed, S., Graf, H. R., and Ziada, S., 2011, “Aeroacoustic Source of a Shallow Cavity in a Pipeline,” ASME Paper No. PVP2011-57437). The merits of these two methods in determining the aeroacoustic sources are highlighted....
Closure to “Discussion of â€کFlow Excited Acoustic Resonance: Excitation Mechanism, Design Guidelines and Counter Measures,’†(Ziada, S., and Lafon, P., 2014, Appl. Mech. Rev., 66(1), p. 010802)

Passive Control of Trapped Mode Resonance of Ducted Cavities
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Gas flow over ducted cavities can excite strong acoustic resonances within the confined volumes housing the cavities. When the wavelength of the resonant acoustic modes is comparable with, or smaller than, the cavity ...
Measurement of the Excitation Source of an Axisymmetric Shallow Cavity Shear Layer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The interaction of a cavity shear layer with the sound field of an acoustic mode can generate an aeroacoustic source which is capable of initiating and sustaining acoustic resonances in the duct housing the cavity. This ...
