2014 (English)In: 21st International Congress on Sound and Vibration 2014, ICSV 2014, international Institute of Acoustics and Vibrations , 2014, 1420-1427 p.Conference paper (Refereed)
The scattering of acoustic plane waves at a sudden area expansion in a duct without flow is simulated using a linearized Navier-Stokes equations solver in frequency domain. The aim is to validate the numerical methodology for three-dimensional simulations, and to investigate the acoustic properties of the area expansion. A comparison of results from numerical simulations, measurements and analytical solutions is presented. It is shown that results for the acoustic scattering obtained by different wave decomposition methods are in excellent agreement.
