Research Topic
Rearrangement processes of particle structures in wall flow filters
Ceramic wall-flow filters are used for the removal of particles from the exhaust gas stream of modern combustion engines. During operation, layer rearrangements occur due to the removal of organic components. These rearrangements can lead to disadvantageous operating behavior, such as an increase in pressure drop.
The aim of this research project is to enable independent fundamental investigations of the interactions between aerosol formation, particle deposition and rearrangement by separating the aerosol generation from the engine combustion process and adjusting a wide range of process parameters. In this way, it is conceivable to specifically relate the processes during deposition and rearrangement to process parameters and aerosol formation mechanisms.
