Particle filtration results from adhesion or sieving of
particles. Both effects may stem from interactions with the filter
material or previously collected particles. To achieve the contact,
and ultimately filtration, the textile media must be designed
appropriately. We will demonstrate algorithms and software that model
the geometric complexity of woven and nonwoven filter media and the
physical complexity of various filter mechanisms in a wholistic
fashion. Worked project examples illustrate the usefulness of these
tools for the optimization of the pressure drop, filter efficiency and
filter capacity.
