By　far,　no　experimental　data　of　convection　heat　transfer　in　ducts　with　molten　salts　may　be　found　in　open　literature.　In　order　to　understand　the　heat　transfer　characteristics　of　molten　salts　and　verify　the　well　know　empirical　correlations　for　molten　salts,　experimental　study　on　turbulent　convective　heat　transfer　with　molten　salts　in　a　circular　tube　was　made.　Molten　salts　circulations　in　the　system　were　realized　and　operated　over　1000　hours　were　obtained.　The　flow　rates　and　temperatures　of　molten　salts　and　mineral　oil　in　the　inlet　and　outlet　of　the　salts-oil　heat　exchanger　were　measured　and　the　average　forced　convective　heat　transfer　coefficients　of　molten　salts　were　obtained　by　least-squares　method.　Finally,　a　heat　transfer　correlation　of　turbulent　flow　with　molten　salts　in　tube　was　obtained　and　good　agreement　was　found　between　the　correlation　and　the　well-known　Colburn　equation　and　Hausen　equation.　Copyright　©　2009　by　ASME.
