Resumo

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.
