ABSTRACT

Free-convection turbulent heat transfer on inclined surfaces at large Rayleigh numbers is analyzed. A relation obtained for the Nusselt number is compared to a wealth of experimental data on heat and mass transfer on vertical, horizontal and inclined surfaces within a wide range of variation of the Prandtl number. The model applies to heat through a wall and in semicylindrical and semispherical vessels with internal heat liberation. A model of an effective turbulent heat conduction is suggested.
