Asymptotic modeling of the wave-propagation over acoustic liners

Dr. Adrien Semin, TU Berlin/ BTU Cottbus

3 May 2018, 17:00–18:30; Location: S4|10-314

We will consider the acoustic wave propagation in a channel separated from a chamber by a thin periodic layer. This model stand for microperforated absorbers which are used to supress reflections from walls. Due to the smallness of the periodicity a direct numerical simulation, e.g. with the finite element method (FEM), is only possible for very large costs. In this talk we aim do describe equivalent transmission conditions for the viscous acoustic equations, which integrated into numerical methods like the FEM or the boundary element method leads to much lower computational costs.
