ABSTRACT
Most correlations were intended to be used for water and industrial gases, but in the 1960s and 1970s, additional correlations were developed for metallic coolants. This chapter discusses these correlations and show how they can be applied to important problems in the field of nuclear heat transfer. Geometric correction factors are then used to convert between heat transfer correlations for circular pipe flow and those for noncircular ones. Perhaps the most famous turbulent heat transfer correlation used for water reactor design is the Dittus–Boelter correlation. Many studies have been conducted to understand how the heat transfer coefficient behaves when a fluid first enters a heated flow channel. The heat transfer correlations for metallic coolants have a slightly different generic form than they do for nonmetallic ones. A steamline sends depleted steam from a steam turbine to a storage building which it heats in the winter.
