Simulation Supporting the Exhaust Aftertreatment Development Process – 1D Concept and Control Design, 3D Detail Optimization

Johann Christian  Wurzenberger, AVL List GmbH

This presentation discusses a comprehensive simulation framework using
1D and 3D simulation tools to investigate diesel exhaust
aftertreatment on both system and component level. On the component
level 3D simulations are performed to investigate the impact of mixing
devices on ammonia uniformity and wall film formation. A 3D detail
analysis is performed on DPF channel flow of open filters. On the
system level, advanced 1D DPF and injector models are presented.
