Nusselt numbers were calculated for fully developed, turbulent, and parallel flow of liquid metals through staggered tube bundles by a method analogous to that of Lyon for flow of liquid metals inside circular tubes. The tubes were assumed to be arranged on an equilateral triangular pitch. A constant heat flux from the outer surfaces of the tubes was assumed, and the model of an annulus was used; i.e., the heat leaving each tube was assumed to be picked up by the flowing metal in an imaginary annulus surrounding the tube, the outer circumference of the annulus circumscribing an area equal to the total cross- sectional hexagonal area associated with each tube. The results were based on the velocity distribution data of Rothfus, Walker, and Whan for flow in concentric annuli. The effects on the Nusselt number of Prandtl number, Peclet number, tube diameter, pitch-to-diameter ratio, and the ratio of eddy diffusivity for heat transfer to that for momentum transfer were determined.
