Virtual performance tests of filter media help to speed up development cycles and to quickly find customer tailored product solutions. In order to achieve virtual filter testing methods with high predictive quality, great care has to be taken to accurately capture the essence of the structure (geometry) and the physical processes. Consequently, we develop models, algorithms and software implementations related to virtual structure generation, geometric structure analysis, fluid dynamics and solid mechanics. To avoid parameter uncertainties, all methods operate on the microstructure of the filter media.
In the present paper, we perform a basic study of weave patterns subject to deformation using our software suite GeoDict and the new elasticity module FeelMath. More precisely, we consider basic weave patterns like plain and twill weave and compute their structural behavior under tension, compression, shear and bending forces. Having undeformed and deformed weaves as computer models, pore morphology changes, permeability and filter performance are computed and analyzed. The results provide fundamental insights into the governing mechanisms on the micro scale and their influence to the filter media scale.
