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…
