Effectiveness of channels with heat transfer intensifiers in the form of protrusions.

The design and model of a channel with heat transfer intensifiers in the form of wide protrusions are developed in a detailed manner. The calculated coefficients of heat transfer and friction resistance are compared with experimental data in a wide range of Re numbers and sizes of protrusions. The optimal geometrical characteristics of such channels are determined, and their advantages over channels of other configurations are shown. [ABSTRACT FROM AUTHOR]
