Fundamental investigations into the influence of temperature and flow velocity on coalescence filtration

Coalescence filters are established elements for droplet separation whose complex mechanisms are still incompletely understood. In view of the increasing importance of energy efficiency and sustainability, optimising energy consumption by reducing pressure loss is of great interest. However, there is a lack of sound knowledge about the effects of increased operating temperatures and reduced flow velocities on the filter properties.

The aim of this research project is therefore to investigate the influence of temperature and flow velocity on fundamental mechanisms of coalescence filtration. To this end, the level of observation is gradually increased from individual fibres to random fibres and full filters. Using measurement technology with high temporal and spatial resolution, the transport and detachment behaviour, coalescence kinetics, liquid drainage and local saturation distributions are determined at micro, meso and macro level. The knowledge gained should lead to a better understanding of the fundamental processes and enable a more energetically favourable application of coalescence filters.
