Nanotomography and High Performance Computing: towards unprecedented predictions in materials and energy

Résumé

This conference is devoted to impressive progresses in material sciences and energy allowed by 3D imaging and High Performance Computing (HPC). High resolution 3D imaging is nowadays part of the laboratory equipment: confocal microscopes are usual lab tools and nano-tomography with sub-micrometric resolution starts to be available in some labs. Similarly, the mushrooming power of computers continues to move the frontiers of simulation. Upscaling methods, such as homogenization or volume averaging, allowed a well-established set of macroscopic equations in heterogeneous media to be obtained. This approach is powerful but needs to be supplied by relevant effective parameters. Nowadays, thanks to the spectacular progresses in 3D imaging and computational tools, these effective parameters can be obtained by 3D calculations on real pore morphologies. Recent examples will be presented to predict properties of bio-based building materials. 3D imaging and HPC are also complementary tools to simulate processes involving coupled transfer in reactive or bioactive media. Some examples of such processes will be proposed in the second part of the conference. The final part of the talk will be devoted to advances in formulation that remain needed to effectively take advantage of these two impressive tools (nanotomography and HPC). For example, new insights in fractional operators will be presented biefly.
