[en] The suitable turbulence model is found to be required in the course of establishing a proper analysis methodology for thermal stripping phenomena. Two different turbulence models of κ-ε model and Full Reynolds Stress (FRS) model, are applied to analyze unsteady turbulent flows with temperature variation. Test case is cross jet sodium flow in pipe with T-junction. Analysis yields the conclusion that 3-D computation with turbulence model is generally able to predict physical characteristics of flow. FRS predicts fast diffusion transport effect. However, modified modeling for near wall effect is required to improve its heat transfer characteristic analysis
