Abstract：

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.　All　right　reserved.
