The benefit of using nano fibers is the improvement with respect to filter efficiency and the relatively low pressure drop due to the nano slip. At the Fraunhofer ITWM, the simulation of filter media and filtration processes is traditionally performed resolving the smallest scale of the media. When entering the nano regime, two problems arise: First, the structures under consideration become huge in terms of computational grids. Hence, special algorithmic approaches have to be followed to overcome this hurdle. Second, the models for fluid flow and particle movement have to be extended by new physical effects like slip flow. The presentation gives an overview on the latest developments concerning nano filtration in the Fraunhofer software suite GeoDict/FilterDict.en003conference paper
