Abstract
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 and more. The increase in the frictional resistance was much smaller.
