Among many analogies (like Reynolds analogy, Prandtl–Taylor analogy) developed to directly relate heat transfer coefficients, mass transfer coefficients, and friction factors Chilton and Colburn J-factor analogy proved to be the most accurate.
In a variety of analogies (including Reynolds analogy and Prandtl–Taylor analogy), which are used to link heat transfer coefficients, mass transfer coefficients, and friction factors, the Chilton and Colburn J-factor analogy emerged as the most accurate among them all.
