Research Topic
Investigation of development, rearrangement, and detachment of reactive-inert particle structures on cylindrical collectors in gaseous environment
Depth filters are used in air-conditioning, cleanroom technology and exhaust gas treatment. Particles are separated inside a porous structure. Detachment of separated particles and stepwise transportation does not happen in most applications. Nevertheless reactive components in deposited particle structures can cause rearrangement and detachment. These processes are relevant in soot particle filtration and therefore fundamental research about this phenomena should be made in this project.

Fiber is inside an air stream with 440°C and 0,4m/s.
