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. An Experimental Study of Chilton–Colburn Analogy Between Turbulent Flow and Convective Heat Transfer of Supercritical Kerosene. Yongjiang Zhang.
This form includes the ratio of the mean velocities in the sublayer and core as well as the Prandtl number for heat transfer.

Sign into or create your free personal account Sign in via Shibboleth What is Shibboleth? The present results show that Chilton—Colburn analogy is also valid for turbulent flow and heat transfer of supercritical kerosene in horizontal straight circular tubes. If a laminar sublayer is included between these, the Prandtl-Taylor analogy applies: Shibboleth is an access management service that provides single sign-on colbutn resources.
Heat transfer enhancement and deterioration were observed in the experiments as well as the similar change of skin friction coefficient. Customize your page view by dragging and repositioning the boxes below.
