The acoustical behavior and the flow in a rectangular lined channel with grazing flow have been investigated. The liner consists of a ceramic structure of parallel square channels and is locally reacting. In the absence of flow, the liner has a classical behavior: the acoustic transmission coefficie

The boundary condition at an impedance wall in a duct with a steady mean #ow requiring the speci"cation of the normal component of acoustic particle velocity is examined. It is found that when implemented in the weak formulation of the "nite element method it can be considerably simpli"ed. The bound
