Abstract

Abstract

To study the influence of different turbulence models and turbulence Prandtl number (Pr_t) models on the simulation of lead-bismuth solidification behavior, this paper uses FLUENT to simulate the flow solidification behavior of lead-bismuth (Pb-Bi) inside a tube. The simulation results show that although the differences between the shear stress transfer (k-ω SST), k-ε and Reynolds stress (RSM) models in simulating Pb-Bi heat transfer can be ignored, there are significant differences in the simulation of the temperature and pressure fields during the phase change, thus the turbulence model should be carefully selected. In addition, the study on the simulation of Pb-Bi solidification using different Pr_t models shows no significant difference.
