Abstract

In order to get a further reduction on pressure loss of a reactive muffler, the interior flow field of the muffler and the generation mechanism of pressure loss are investigated by the CFD method. Then, the influences of the insert tube length on the acoustic and aerodynamic performance of the expansion chamfer muffle are discussed. Results show that the spatial location of expansion or compression vents are so extremely important for the acoustic modes that one can adjust their locations to promote the acoustic and aerodynamic performance of the reactive muffler
