Abstract
Simulation represents an important resource for the design and optimization of close-coupled exhaust system components in the context of product development and close-toproduction product support. This article examines the status of simulation techniques for the efficient application of steady-state and transient 3D CFD flow analyses with boundary conditions derived from 1D gas exchange simulation data. An example will show how the combination of methods can supply valuable information at an early design stage and how it can be used as a powerful tool for the evaluation of system-inherent problems.
