To characterize, analyze and evaluate an assembly, a material or a product without outside changes is a common wish in engineering and natural sciences.
For this purpose, microcomputertomography (µCT) can be used as it is a not-destructive image-processing evaluation method that is based on the weakening of X-rays via absorption and scattering effects in the material. Based on a series of X-ray pictures, a 3D visualization of the material structure within the body is calculated on high-performance computers. Therefore, the object can be evaluated in very high resolution. Due to its versatility, we apply tomography-based simulation as cross-sectional technology within the research group of material and energy technologies.
In particular, we use the exact knowledge on microstructures for a better understanding of complex physical properties of a material. Realistic modelling and simulation of numerous processes is possible with this knowledge. Exemplarily, we use tomography to analyze the growth and degradation of clathrates and to evaluate heat transfer and mass transport in porous media like insulation.
As material parameters can be easily accessed and modified, computational models help us to optimize existing materials and to design new ones. We apply open-source solvers as well as in-house numerical solvers, which are optimized for coupled simulations and large computational grids.
