Investigating the Feasibility and Stability for Modeling Acoustic Wave Scattering Using a Time-Domain Boundary Integral Equation with Impedance Boundary Condition
… impedance. Converted into the time-domain using Fourier transforms, an impedance boundary condition can be used to simulate the acoustic wave scattering by geometric bodies treated with acoustic liners</p> <p>This work considers using either an impedance or an admittance …

Implementing and testing a panel-based method for modeling acoustic scattering from CFD input
… may be obtained using CFD plus surface integral methods such as the Ffowcs-Williams Hawkings method, the scattered sound field is complicated by its dependence on the geometry of the scattering surface---the aircraft carrier deck, aircraft control surfaces and other nearby structures.</p> <p>In …
