摘要

Presented in this paper are the results of measurement of the main two-phase flow characteristics. The investigation of phase velocities distribution over the tube cross-section is performed by means of an isokinetic sampling probe, of void fractions by means of the γ-ray attenuation method, of shear stresses at the channel wall with the use of the movable sleeve, of liquid film thickness with the help of the electric resistance probe. The total hydraulic resistance measurement is carried out by means of the commonly used technique. The experiments are carried out for the pressures ranging from 6.86 to 13.7 MN/m2 and mass velocities from 500 to 1000 kg/m2s. On the base of an analysis of the experimental material a physical model for the hydraulic resistance calculation is proposed.
