THE RESEARCH OF TEMPERATURE CONDITIONS OF SMALL DIAMETER PARALLEL TUBES COOLED BY WATER UNDER SUPERCRITICAL PRESSURES
要約
The results of experimental research of deteriorated heat transfer generation mechanism in the bundle of 5 parallel 3 mm ID 750 mm length tubes under stable and pulsating conditions of cooling liquid flow are presented.
The tests were performed at the pressures of 22.6, 25.5 and 29.4 MN/sq m in the range of mass velocities from 450 to 3000 kg/sq m s and of flow inlet enthalpies from 420 to 1400 kJ/kg. The value of heat flux achieved 3 MW/ sq m, Chemically desalted and deairated water was used as a cooling liquid.
