Colligation of Experimental Data on Heat Transfer in Liquid Metals*

Abstract

The experimental data on heat emission in turbulent flow of a liquid metal in a tube, including data on mercury, sodium, and the alloys Na–K and Pb–Bi, are examined. A universal profile of the temperature distribution in the form of the dimensionless variables T⁺= f(y⁺⁺), approximated by three equations of which one is logarithmic, is obtained. On the basis of these relations, a relation is found in the form Nu = f(Pe), which is accurate to within ±8%, for use in engineering calculations.
