Fraunhofer-Institut für Techno- und Wirtschaftsmathematik ITWM

The Fraunhofer Institute for Industrial Mathematics ITWM has years of experience in modeling and simulating filtration processes and production processes of filter media.

The development cycle of new products is shortened; the number of prototypes of filter media is reduced. Virtual nonwoven are generated, visualized and optimized with “GeoDict”. “FilterDict” performs filter efficiency and life time simulations in generated nonwoven. "PoroDict" predicts pore size measures. Results are processed in MS-Excel. By modifying material parameters (porosity, anisotropy, fiber diameter, crimp, fiber shape etc.) and repeated simulation, improved media designs are achieved. “SUFIS” designs new filter housings, finds optimal locations for the filter media and computes the flow-pressure relation.
