The aim of this work is to investigate the influence of the ash-soot ratio on the rearrangement processes of reactive and inert 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 the particle layer by filtering varying mixtures of soot and ash particles.
The parameters to be investigated include the reactive-inert ratio (100% reactive, 25% inert - 75% reactive, 50% inert - 50%, 75% inert - 25%) and the particle loading. The regeneration of the soot particles breaks up the particle layer, which leads to the formation of resuspendable particle structures. These structures are analyzed with regard to 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.
