要約

An experimental study was performed on heat transfer of liquid sodium flowing through concentric and eccentric annular channels with an inner to outer radius of 0.576. Measurements were performed over a range of Reynolds number from 18,000 to 113,000 for a Prandtl number of 0.007 under the condition of the heating inner wall and the adiabatic outer wall. A sheathed thermocouple probe was set in the test section for measuring temperature distributions transverse to the sodium stream. In the case of the concentric condition, turbulent thermal diffusivities, at, and mean Nusselt numbers were compared with the results of some works previously reported. The eccentric condition measurements were made for the reduction in mean Nusselt number, and the results were compared with the predictions of Yu and Dwyer.
