Abstract
The performance of silencer system is controlled by the geometrical parameters such as the relative location of inlet and outlet ports, size of main chamber, and cross sectional geometry of inlet-outlet ports and main chamber of silencer. In addition to these parameters, the presence of mean flow and temperature gradient along the silencer also affects the acoustic characteristics of silencer system. Due to the complexity of silencer, it is not straight forward to design the appropriate silencer system. In this paper, a design methodology based on an oustic analysis of silencer system is proposed ; low frequency and high frequency tuning method.
