Acoustic wave transmission on homogenized perforated plate
Abstract eng: We consider problems of the acoustic wave propagation in an inviscid fluid through a rigid periodically perforated plate. Using the homogenization method the wave propagation in a layer containing the plate is replaced by transmission conditions which couple the acoustic field on both sides of the plate represented by a flat interface. The interface impedance depends of the shape of the perforation. For suitable shapes of the holes, there is a coupling between transverse and surface acoustic waves propagating along the panel. The derived model leads to a significant savings in the computational cost of the numerical solutions.
