Abstract [en]

Despite many advances in computational fluid dynamics (CFD), heat transfer modeling and val-idation of code for liquid metal flows needs to be improved. This contribution aims to providevalidation of several turbulence models implemented in OpenFOAM. 6 different low Reynoldsnumber and 3 high Reynolds number turbulence models have been validated against experimen-tal data for 3 different Reynolds numbers. The results show that most models are able to predictthe temperature profile tendencies and that especially the k-ω-SST by Menter has good predic-tive capabilities. However, all turbulence models show deteriorating capabilities with decreasingReynolds numbers.
