Abstract
An analysis of the experimental results for heat transfer on convex and concave walls of slotted spiral channels as well as for local heat transfer around the periphery and along the tube of the coils is presented. Great attention is paid to examining surface friction and its pulsations on the hydrodynamic entrance section and under stabilized coil flow conditions. The transition from laminar to turbulent flow on the convex and concave walls of slotted spiral channels and around the periphery of the tube of different-curvature coils is analyzed.
