In this study, we run simulations on a filter structure with different pleat counts and volumetric flow rates. We find find the local minimum of the pressure drop and the ideal configuration between filter area and pleat count.
In the case study shown here, the microstructure of a two-layer filter medium of an existing face mask is analyzed. The microstructure is the result of importing and segmenting µCT scans of the filter medium in GeoDict. The scan resolution is 400 nm.
