Abstract

Silencers have widespread applications. In industrial settings they are used at large-scale combustion, gas turbine, blower and compressor system junction points to control noise. The most common methods of noise elimination via silencer are varying of the size and cross-sectional area of the transmission pipe such that during sound wave transmission, non-uniform impedance is produced. Partial sound wave reflection is an echo source or consumes the energy of transmitted sound waves to achieve noise elimination. In this study, COMSOL Multiphysics, commercial finite element analysis and simulation software, was the main analytical tool. The aim of this study was to investigate the effects of variations in silencer structure on acoustic attenuation. Based on finite element method simulation, the optimal silencer geometry for noise cancellation was determined.
