Progress & Challenges predicting Filtration and Separation.

Abstract 

Filtration is a phenomenon determined by multiple scales.  They range
from the flow regime around a moving vehicle to the atomic regime of
adhesion forces between dust particles and an electrically charged
filter medium. Fortunately, powerful computers, sophisticated models
and new experimental equipment are available.  Desktop computers with
lots of memory and several fast CPUs, three-dimensional filter media
models combined with REM and ÁCT images are some of the exciting
developments that allow modeling and simulation work today that was
unthinkable in the past.  The talk will present examples how detailed
three-dimensional filter media models, filter process models, CFD and
statistics can provide valuable insights into filtration from both the
practical and the academic point of view.  It finishes with an outlook
on how this work may also be applied in underground contaminant
transport and someday even reactive flows.
