Studies of Swirling Annular-mist Two-phase Flow : 2nd Report, Analysis of Liquid Film Flowrate Along a Tube

Abstract

The liquid film flowrate along a tube (40 mm ID, 5 m length) in swirling downward annular-mist air-water flows, induced by different swirlers at the inlet of the test tube in each run, was measured. The effects of the angle of torsion and length of swirlers, the gas velocity, and the liquid flowrate on the liquid film flowrate along the tube were clarified by experiments. A theoretical analysis of the liquid film flowrate at an outlet of swirler and along a tube was conducted. The calculated results agreed well with the experimental results.
