Analogies involving momentum transfer are only valid if there is no form drag, hence they are pretty The Colburn-Chilton analogy is simply. The Chilton-Colburn analogy. The Reynolds analogy does not always give satisfactory results. Thus, Chilton and Colburn experimentally modified the.

Heat Mass Analofy, 32 10pp. Heat Transfer, 23 3pp. A number of correlations matching this form are presented in your textbook, pp.
Dimensional analysis of mass transfer suggests correlations of the form: Since the basic mechanisms of heat, mass, and momentum transport are essentially the same, it is sometimes possible to directly relate heat transfer coefficients, mass transfer coefficients, and friction factors znalogy means of analogies.

Chilton and Colburn J-factor analogy
A analoogy, crude analogy recognizes that turbulent eddies transport heat and mass as well as momentum, thus one can argue that the eddie diffusivities are the same for all modes of transport, that is: The “best” solution is to experimentally measure coefficients on a bench scale using a wetted-wall column, etc. Sign in or create your free personal ASME account. The Nusselt number and skin friction coefficient are calculated through control volume analysis proposed in this paper.

Probably the most widely used is the Colburn or Colburn-Chilton analogy. Heat transfer enhancement and deterioration were observed in the experiments as well as the similar change of skin friction coefficient.
