Transfer Matrix Coupling Approach for Predicting the Acoustic Performance of a Complete Aftertreatment Exhaust System 2014-01-2056
The tailpipe noise from an aftertreatment system must comply with legislation and meet customer expectations. The approach to capture the influence of complicated geometries and the ceramic substrates included in full aftertreatment systems (ATS) is implemented by coupling the 1D analytical solution of the substrates with the 3D FEM solution. The simulations are verified with measurements in a flow acoustic test rig.
