Acoustic scattering simulations in coupled fluid-porous media problems

Ashwin Nayak; Andrés Prieto; Daniel Fernandez-Comesaña

Sound-intensity sensors are sensitive to flow conditions and utilize porous windscreens to mitigate induced noise. Introduction of an effective windscreen requires development of a coupled mathematical model accounting for acoustic transmission across the porous media layer around the probe. We utilize the finite element method along with perfectly matched layers to study the scattering of a plane wave by such representative configurations under no flow conditions.
