Comparison of Noise Attenuation Level by Convergent and Divergent Cylindrical Duct with Space Constraints

Authors(1) :-Amit Kumar Gupta

This paper shows the details of comparison of noise attenuation level by convergent and divergent cylindrical duct with space constraints by using Transmission loss parameter. Reactive muffler is noise reduction element on exhaust system. Two basic term is used for noise attenuation first is transmission loss (TL) and other is insertion loss (IL). The main aim of this paper is to use of TMM, FEA (Wave 1-D & Comsol) as well experimental method (two load method) for muffler’s TL measurement for central inlet and side outlet position. Afterword to achieve by proven results analysis is done for convergent and divergent cylindrical duct. Also FEA based tool Comsol Multiphysics and Wave 1-D is used to validate and comparing the results. FEA tool is used for virtual prototyping which has already validated with various case studies. Also by comparing the experimental results by fabricated muffler with FEA results for central inlet and central outlet shows the validation of results. So the optimization can be achieved by using FEA tool by using virtual protyping.
