3D Analysis

3D analysis, modeling and simulation of the microstructure and transport processes in fiber-based porous materials


In this collaborative project funded by the Federal Ministry of Education and Research (BMBF), stochastic and numerical methods from applied mathematics are developed and combined in order to analyze challenging problems in industrial materials science. Microstructure models of stochastic geometry (Ulm University) and numerical Lattice Boltzmann transport models (Forschungszentrum Jülich) for fiber-based porous materials are combined to achieve a better understanding of the effect of 3D morphology on the mass transport processes in these materials. The results of this integrated mathematical modeling will be used for the development and implementation of efficient simulation algorithms for virtual scenario analyses using the supercomputers at Forschungszentrum Jülich to simultaneously perform high-resolution analyses of 3D material structure and mass transport over large areas.

The aim is to identify morphological microstructures which are beneficial for mass transport. As an example, the findings of this virtual material design are to be applied in the investigations of gas diffusion layers manufactured by FFCCT from non-woven material and will be used to improve them as components in polymer electrolyte fuel cells (PEFCs). In order to apply the models for virtual material design, 3D data sets from synchrotron tomography (TU Berlin and BAM) and the 2D data sets of real materials more readily available in industrial applications are used as a basis for mathematical modeling and simulations. The adaptation and comparison of the geometric characteristics of the structural models and image data lead to simulations with a high predictive power.
