“…The following and Sideman [2] have derived theoretical Nusselt numbers for dimensionless correlation was proposed: the case of heat transfer to liquid metals flowing past a Nu D ϭ 2 ϩ 0.386 ϫ (Re ϫ Pr) 0.5 [4] For [3.56 ϫ 10 4 Ͻ Re Ͻ 1.525 ϫ 10 5 , Pr Ϸ 0.004] [2], respectively, do not correlate well with his experimental data with respect to sodium. Witte's [4] findings also bring to the forefront another important consideration, namely, the difference in the convective heat-transfer characteristics between water and liquid sodium. The author has shown that the results obtained using liquid sodium were appreciably lower than those obtained from a correlation derived from experimental work with water.…”

Two main objectives were addressed in this article. First, a dimensionless heat-transfer correlation for single-phase flow forced convection in liquid aluminum has been derived using a novel experimental method. An aluminum sphere was rotated with a specific tangential velocity in liquid aluminum. Its melting time was measured and correlated with the convective heat-transfer characteristics. The resulting correlation has the following form:The second objective of the study was to assess the accuracy of various correlations using an annular channel, which was available at an independent setting, at the Alcan Research and Development Laboratory. The correlations investigated were those derived from the current experimental work as well as those derived by other investigators, as presented in their respective published work. Results indicated that when applied to liquid metals, theoretically derived equations as well as equations developed for fluids with a Prandtl number greater than 0.7 exhibit a very large error. As such, these equations are unsuitable for liquid metals. A considerably smaller error is exhibited by equations derived experimentally, specifically for liquid metals, thereby attesting to the careful consideration that must be exercised in the choice of correlations that are employed.This study also provides a critical assessment of various exponents used in dimensionless equations for convective heat transfer in liquid metals. While there is a general consensus that the exponent of the Reynolds number is around 0.5, the exponent for the Prandtl number varies considerably.
