Modeling of Forced Convection Heat Transfer to Lead-Bishmuth Eutectic in OpenFOAM

• In this publication several turbulence models which are implemented in OpenFOAM are validated against experimental data for heat transfer in a lead-bismuth-eutectic flow. The results show that with decreasing Reynolds number the heat transfer predictions degenerate. With lower than standard constant Prandtl number the heat transfer predictions become better. Overall, one can say that the predictions by the k-omega-SST model by Menter (from 2003) give the best predictions, but also need the finest grid (about 2.5 times more cells than comparable models).
