The Analogy Between Fluid Friction and Heat Transfer

Abstract

The results of the modern turbulence research on velocity distribution near solid walls are applied to extend Reynolds’ analogy between fluid friction and heat transfer to liquids. Discrepancies between the experimental results and the theory of Taylor and Prandtl are explained. A new theoretical formula which fits the experimental results more satisfactorily is suggested and compared with the empirical equations of Dittus and Boelter.
