The aim of this work is to investigate the influence of different regeneration conditions - active O₂ regeneration versus passive NO₂ regeneration - on the rearrangement processes of soot and ash particles. For this purpose, an existing test rig is used, which enables both the generation and dispersion of these particles. A specially designed model filter channel is used to form a particle layer by filtration from soot.

On the one hand, the regeneration conditions (active O₂ supply compared to passive NO₂ treatment) are being investigated. The regeneration of the soot particles breaks up the particle layer, which leads to the formation of resuspendable particle structures. These structures are analyzed in terms of their number, size and development over time.

The detachment and resuspension events are documented using a high-speed camera (1000 images per second). The aim of the work is to determine the conditions under which particle structures can be detached and resuspended in order to gain a better understanding of particle rearrangement in filtration systems.
