Time-domain implementation of an impedance boundary condition with boundary layer correction
(ElsevierJournal of Computational Physics, 2016-06-08)A time-domain boundary condition is derived that accounts for the acoustic impedance of a thin boundary layer over an impedance boundary, based on the asymptotic frequency-domain boundary condition of Brambley [2011, AIAA ...
