Аннотация

This article presents an analytical overview of experimental studies of hydraulic resistance and heat transfer in channels with disturbed flow surfaces in the form of systems of spherical protrusions in a wide range of flow and design parameters. A uniform approach to generalization of experimental data by various authors has been developed considering differences in the geometry of heat-transfer surfaces. Uniform universal generalizing dependences have been obtained for the hydraulic resistance and heat transfer coefficients in channels with spherical protrusions.
