The radial temperature distribution in a -30 mm stainless steel tube was determined for alkali metal at Reynolds number of 16,200 and 24,700 and at heat flows of 40,000 and 39,500 kcal/m/sup 2//hr, and for heavy metals at Reynolds numbers of 24,200 and 204,000 and at heat flows of 17,800 and 41,000 kcal/m/sup 2/ /hr. The wall temperature which was required to calculate the heat transfer coefficient was determined by extrapolating the temperature profile of the liquid metal to the temperature of the wall. The data fit the formula of R. Lyons over a wide range of Peclet numbers of 100 to 12,000: Nu = 7 + 0.025 Pe/sup 0.8/. However, if the contact thermal resistance due to the oxide film on the heavy metals is taken into account, the points for the heavy metals fall below the curve for the liquid alkali metals on a plot of Nusselt numbers versus the Peclet numbers. The contact thermal resistance for the heavy liquid metal is plotted as a function of the Reynolds number. Chemical analysis showed that the content of oxide near the wall was about a factor of ten greater than the content of oxide in the main stream of the heavy metal. (TTT)
