The authors carried out an experimental investigation 
of heat transfer in the supercritical zone in flow of water and a 
steam-water mixture in a vertical annular channel. The interior wall 
heated by the current was either smooth or with hollows stamped in 
a straight-line order. The application of them increased the heat-transfer 
coefficient by a factor of 1.5-2 or more. The increase 
in the frictional resistance was much smaller.
