3D Acoustic Modelling of Dissipative Silencers with Nonhomogeneous Properties and Mean Flow
A finite element approach is proposed for the acoustic analysis of automotive silencers including a perforated duct with uniform axial mean flow and an outer chamber with heterogeneous absorbent material. This material can be characterized by means of its equivalent acoustic properties, considered c...
