Turbulent Heat Transfer upon the Suppression of Near-Wall Turbulence and the Relation between Heat Transfer and Friction Drag

详细

The paper presents an analysis of previously obtained experimental data on a stronger reduction in turbulent heat transfer in comparison with the momentum transfer upon the suppression of near-wall turbulence. In this case, the heat transfer decreases much more than the friction drag. Three groups of such data are considered: the initial stage of the thermogravitational effect on forced convection in vertical pipes, motion contraction, and the effect of polymer additives.
