3D Global Weak-Form Mesh-Free Method for Acoustic Attenuation Analysis of Expansion Chambers
In order to avoid the dependence of mesh method on grids, a 3D global weak-form mesh-free method (MFM) is applied to study the three-dimensional acoustic characteristics of silencers. For the expansion chamber silencers, the 3D acoustic modes are extracted and the transmission loss results are compu...
