Numerical Simulation of reacting multiphase flow and high-temperature processes
Numerical simulation has been established as an essential scientific discipline in the past decades, which bridges the gap between experiment and theory. Computational design and optimization have a high potential to significantly reduce the time scales and investment costs of the development processes of new products.
Highly-resolved numerical simulations accompanied by high-performance computing (HPC) techniques are extensively used to study reacting multi-phase flow and high-temperature processes at ITC, for instance, for pyrolysis, gasification and combustion. The multi-physics, multi-phase and multi-scale simulations of such processes, with timely and spatially resolved chemical-physical fields provide a detailed insight into the underlying chemo-physical mechanisms as well as their mutual interactions. The knowledge gained from said numerical simulations can be beneficially used for process optimization and intensification.
