In this paper, the e!ect of grazing}bias #ow interaction on the acoustic behavior of a perforated plate is investigated. In the experiment, bias #ow into or out of ori"ces (in#ow or out#ow) is used to change the acoustic impedance of the test perforated plates subjected to grazing #ow, and the acous

The study of the acoustic effect of perforated plates by Large-Eddy Simulations is reported. The ability of compressible Large-Eddy Simulations to provide data on the flow around a perforated plate and the associated acoustic damping is demonstrated. In particular, assumptions of existing models of
