Abstract
The authors give results of measuring the hydraulic resistance, heat transfer, and temperature fields at the numbers Re=70–3·104 and Pr=5.5–8 for cooling systems with rectangular channels with different kinds of discontinuity of their walls involving additional channels that act as intensifiers of heat transfer. The regions of Re numbers in which this intensification is energy-profitable are revealed.
