Experimental Confirmation of an Analytical Model of the Sound Propagation in a Rectangular Duct in the Presence of Impedance Transitions and Development of an Impedance Eduction Method Based on it
Autor: M. A. Yakovets, M. S. Ipatov, Nikolay Ostrikov
Publikováno v: Acoustical Physics. 66:105-122
The authors have carried out a systematic study of the accuracy in the impedance eduction of liners in “interferometer with flow” rigs in the absence of grazing flow. A method is proposed for determining the confidence interval of sound pressure

Radiation of Sound from the Open End of a Duct Simulating an Air Inlet under Static Conditions and in a Flow
Autor: A. E. Kruglyaeva, M. A. Yakovets, M. S. Ipatov, Nikolay Ostrikov, S. Yu. Sidorov, V. F. Kopiev
Publikováno v: Acoustical Physics. 65:76-89
The paper presents the results of comparative experimental studies on the effect of a significant difference in the radiation patterns of individual acoustic modes from an open duct in steady-state and in-flight modes in the AC-2 anechoic chamber. Wh

Application of the Wiener–Hopf method for describing the propagation of sound in cylindrical and rectangular channels with an impedance jump in the presence of a flow
Autor: A. F. Sobolev, M. A. Yakovets
Publikováno v: Acoustical Physics. 63:625-636
Exact solutions to problems of the propagation of acoustic modes in lined channels with an impedance jump in the presence of a uniform flow are constructed. Two problems that can be solved by the Wiener- Hopf method—the propagation of acoustic mode

Flow noise in a corrugated pipe in terms of the theory of instability waves
Autor: M. A. Mironov, M. A. Yakovets, Victor Kopiev
Publikováno v: Acoustical Physics. 61:499-503
An air flow through a pipe with a corrugated inner surface is accompanied by the generation of a tone (multitone), i.e., coherent, acoustic signal. The main processes giving rise to such a generation include the forced excitation of the active medium
