要約

Reported are the experimental results of studies of statistical characteristics of temperature pulsations in a two-phase flow after dry-out in post-burnout region. The following statistical characteristics have been investigated: intensity, probability distribution density, auto-correlation function and spectral-density. Flow temperature pulsations have been measured with microthermocouples. The tube was 10 mm in inner diameter; the pressure used was 137.3 bar for mass velocities of 350, 500 and 700 kg/m2s. The maximum of relative flow enthalpy in the experiments has not exceeded ΔH/r = 2.
