The acoustic attenuation and acoustic pressure levels of a single-cylinder diesel engine are computed using COMSOL Multiphysics tool to evaluate the performance of the reactive muffler. To increase the travel of exhaust gas, internal modifications in the geometry of the muffler has been done. The experimental analysis shows that the pressure drop for the new developed model is much lesser than that of the existing model for same conditions. CFD approach is employed to investigate the effect ofdoi:10.1007/s42452-020-2683-6 fatcat:qu3inoui3rayxan3bhsuybqrgy
