Multiscale Coupling of System Thermal Hydraulic with CFD-Codes

KIT research work is focused on the multiscale coupling of the system thermal hydraulic code TRACE with different CFD codes e.g. TrioCFD and OpenFOAM using the ICoCo-Approach based on either domain overlapping and domain decomposition.
