Abstract

The feasibility of using simplified theoretical modeling equations was studied as a preliminary step in the design process for exhaust muffler systems. In particular, the results were compared to the results of a computer model. Furthermore, the results of a relatively simple computer model were then compared to the results of a very complex computer simulation model of a muffler system complete with a modeled internal combustion engine as the source. As a result, the merits of using the fundamental equations for preliminary design considerations for muffler systems were demonstrated.
