| Sumario: | The analytical simulated results have been done using Matlab simulations. The numerical simulations have been performed using Finite Element Method in Comsol Multiphysics. The schemas and photos have been based on the printed prototype muffler and the experimental set-up. The experimental data have been adquired in a aero-acoustic test bench. The metasilencer has been located between two rigid duct sections, 1m long, with outlet cross-sectional area 0.075 m x 0.075 m. The two-source and eight-microphone method has been used to determine the scattering matrix of the silencer in the general case of grazing flow. A complete description is provided in the corresponding publication. |
