J Factor is a dimensionless factor for heat transfer coefficient for calculating the heat transfer coefficient in the design and performance prediction of heat exchangers.
Reference Definition by Wikipedia: Chilton–Colburn J-factor analogy is a successful and widely used analogy between heat, momentum, and mass transfer. The basic mechanisms and mathematics of heat, mass, and momentum transport are essentially the same. 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.
