Simulation and experimental results show that the natural convection heat transfer of water in a cylinder tank fits well with Garon＇s correlation. However, significant deviations occur when Garon＇s correlation is used to predict the natural convection heat transfer of molten salt because of its high viscosity and low thermal conductivity. However, the simulated data of the natural convection heat transfer of molten salt fit well with those of the experimental results Thus, a correlation that considers the effect of variable physical properties is proposed in this study to predict the natural con- vection heat transfer of molten salt. The deviation of the present data from the proposed correlation is less than ＋20%. The re- sults of this study can serve as a basis for the design of single energy storage tanks.展开更多
