摘要：
In order to understand natural convection heat transfer of molten nitrate, natural convection heat transfer of lithium nitrate (LiNO3) and multi-components nitrate around a horizontal cylinder with different diameters (0.1, 0.4, 1, 4, 10, 40 mm) at different medium temperatures (573, 623, 673 K) was studied by simulation. The results fitted best with the Fand's correlation comparing with different classic correlations. After analysis of all calculated data, a simple correlation was proposed for predicting laminar natural convection heat transfer of molten nitrate around a horizontal cylinder. Compared with the natural convection experiment data of LiNO3, the proposed correlation had a maximum uncertainty of ±20%, and the reliability of the proposed correlation was verified. ©, 2015, Chemical Industry Press.
