Investigations of an effective time-domain boundary condition for quiscent viscothermal acoustics
Linus Hägg, Martin Berggren
Accurate simulations of sound propagation in narrow geometries need to account for viscous and thermal losses. In this respect, effective boundary conditions that model viscotherma…

Acoustic boundary layers as boundary conditions
Martin Berggren, Anders Bernland, Daniel Noreland
The linearized, compressible Navier-Stokes equations can be used to model acoustic wave propagation in the presence of viscous and thermal boundary layers. However, acoustic bounda…
