Full Acoustic Simulation of Automotive Aftertreatment Systems - Presentation

In analyzing muffler designs, engineers require accurate internal acoustic pressure distributions to determine critical dimensions of the aftertreatment system. Such a tool can help determine far-field sound levels for final pass-by noise validation. Cummins realized significant progress in accurate acoustic modelling of complex aftertreatment systems. Heavy emphasis on automation makes the analysis procedure computationally efficient and simple to implement.
