In this paper, the unsteady 2-dimensional turbulent flow model for thermal stratification in a pressurizer surge line of PWR plant is proposed to numerically investigate the heat transfer and flow characteristics. The turbulence model is adapted to the low Reynolds number model (Davidson model). The dimensionless governing equations are solved by using the SIMPLE (Semi-Implicit Method for Pressure Linked Equations) algorithm. The results are compared with experimental results of TEMR Test. The time-dependent temperature profiles in the fluid and pipe wall are shown with the thermal stratification occurring in the horizontal section of the pipe. The corresponding thermal stresses are also presented.
