Abstract
Reviewed equations for calculation of heat transfer coefficients from a smooth surface, obtained with the use of models of the turbulent boundary layer Prandtl and Deisler. It is shown that the inclusion of disturbances in the boundary layer (roughness of the walls, ledges, ring rolling) can be performed parametrically by adjusting the dynamic speed, the thickness of a viscous sublayer and boundary layer thickness. The results of calculations of the average values of heat transfer coefficients (in dimensionless form of Nusselt numbers and Stanton) and comparing with k nown experimental data.
