Liquid-metal heat transfer in a cocurrent- flow, double-pipe heat exchanger is investigated [PDF]

open access: yes, 1969
Analysis of liquid-metal heat transfer in cocurrent-flow, double-pipe heat exchangers shows that heat-transfer coefficients depend upon the operating conditions of the heat exchanger and that use of the customary design equation to predict heat-exchanger
