Benchmarks for microstructure-based modelling of sound absorbing rigid-frame porous media
Abstract : This work presents benchmark examples related to the modelling of sound absorbing porous media with rigid frame based on the periodic
geometry of their microstructures. To this end, rigorous mathematical derivations are recalled to provide all necessary equations, useful relations, and formulas for the so-called direct multi-scale computations, as well as for the hybrid multi-scale calculations based on the numerically determined transport parameters of porous materials. The results of such direct and hybrid multi-scale calculations are not only
cross verified, but also confirmed by direct numerical simulations based on the linearised Navier-Stokes-Fourier equations. In addition, relevant
theoretical and numerical issues are discussed, and some practical hints are given.
