A theoretical analysis of heat transfer to liquid metals in parallel flow through a tube bundle, following the method of Lyon, results in an equation which agrees within 10% with the calculated values. The conditions are fully developed turbulent flow, constant heat flux at the wall, and an infinite number of tubes arranged on an equilateral triangular pitch. The hexagonal flow area assignable to any tube is approximated by a circle of equal area, and the velocity distribution of Bailey for an annulus is assumed to apply from the inner wall to the circle of maximum flow. The range of conditions is: pitch‐to‐diameter ratio, 1.375 to 10; Reynolds number, 10 4 to 10 6 ; Prandtl number, 0 to 0.1; and Peclet number, 0 to 10 5 . Laminar and slug flow Nusselt numbers are also determined.
