摘要：
Abstract: This paper uses the finite element method (FEM) to study sound propagation in installations of the “interferometer with the flow” type in order to solve the problem of impedance eduction, taking into account the inhomogeneity of the flow for the two-dimensional and three-dimensional geometries of the installation duct. The propagation of sound in a duct in the presence of a plane-parallel airflow is described by a linearized Euler equation, which is solved by the FEM for the given sound frequency. A comparison of the experimental and calculation results demonstrates the effect of the calculated duct geometry on both the distribution of the sound field and the educed impedance values. © 2023, Pleiades Publishing, Ltd.
