An experimental investigation was performed for turbulent heat transfer to liquid sodium in the thermal entrance region. The main characteristicparameters in the experiment are the diameter ratio of the annular d2/dL= 1.54
heat flux g=50W/cm2
Reynolds number Re = 2 × 104- 1.5×105
Peclet number Pe= 122 -1078. The experimental results were found to be in good agreement with theoretical prediction. Finally
some empirical relations were obtained for the Nusselt numbers in fully-developed region and in the thermal entrance region respectively and for the length of the thermal entrance region of turbulent flow of liquid sodium:
