AbstractThe paper proposes methodology and design of the stand which allowed to conduct thermal tests of longitudinally-finned tubes of separators-superheaters for nuclear power plants with water-water power reactors of high efficiency. According to the results of tests of longitudinally ribbed pipes with the number of U-shaped ribs equal to six and eight, a comparative analysis is conducted. It is shown that the increase in heat transfer surface exceeds the decrease in heat transfer coefficient for such structures.
Keywordsheat exchange tubes, separator-superheater, thermal hydraulic tests, heat transfer coefficient, heat exchange surface.
