1ETH Zürich, Zürich, Switzerland

Periodical architected structures comprising reticulated beams or trusses have proven capable of controlling wave propagation at different frequency scales. Moreover, recent progress in 3D printing techniques has paved the way to their actionable application in various fields, i.e., ... Mehr lesen

Duct silencer modeling with COMSOL Multiphysics®

J.A. de Jong1
1ASCEE, Nijverdal, Netherlands

Duct silencers are used to reduce noise in Heating, Ventilation and Air Conditioning (HVAC) as well as noise from exhaust gas chimneys. For a duct silencer, an important trade-off has to be made between the achieved noise reduction and the pressure drop. Using an example model, we will ... Mehr lesen
