Koschatzky, V. (author), Westerweel, J. (author), Boersma, B.J. (author)The aim of the present study is to compare two different acoustic analogies applied to time-resolved particle image velocimetry (PIV) data for the prediction of the acoustic far-field generated by the flow over a rectangular cavity. We consider the model problem of sound radiating from an open, two-dimensional, shallow cavity with an aspect...journal article 2011

Parente, C.A. (author), Rademaker, E.R. (author), Sarin, S.L. (author)From the in-flight measured circumferential modal spectra of the Rolls-Royce Tay 650 engine mounted on the Fokker 100, it was found that the sound field propagating upstream in the inlet is strongly modulated by intercostal hard-walled strips in the lined area, the non-cylindrical geometry of the duct, and the non-axisjnmnetric flow velocity...report 1996

van der Wal, H.M.M. (author)A study has been carried out on the errors, connected with acoustic intensity measurements, measuring the sound transmission loss of panels with the intensity method. The magnitude of some measuring errors can be estimated from available publications. From measurements in a standing wave tube and on a flat plate the measuring errors have been...report 1988
