Abstract (fachliche Beschreibung):

The project was a cooperation of a group of applied mathematicians with
the Russian company Aeroservice for the development and optimization of
new photocatalytic filter systems for air cleaning of nanoparticles and
organic substances with the help of mathematical simulation tools. For
the simulation of aerosol transport in the filter made of polypropylene
fibers, which is used in hospitals or airports, e.g., mathematical
models and efficient solution algorithms had to be developed. These
allow on the one hand to take stochastic components into account, as the
heterogeneous conductivity distribution in the filter. On the other
hand these methods were coupled with highly accurate computation schemes
as mixed finite element methods, which guarantee local mass
conservation for the transport processes. The design parameters of real
experiments can be optimized with the help of such simulation tools and
their sensitivity with respect to filter efficiency analysed. Among the
used methods are particle filtration in porous media, based on the Darcy
equation, and coupled Eulerian and Lagrangeian simulation of transport
processes, including Monte Carlo approaches with given filter
