Level Swell and Flooding of R 113 Two-Phase Mixture with a Falling Film in Vertical Pipes

摘要

Using R 113 vapor and liquid, behavior of the two-phase mixture level was examined in both cases of bubbling a stagnant liquid column in vertical pipes and bubbling a liquid column to which liquid was supplied as a falling film. The pipe diameters used were 10.0, 14.8, 20.2 and 26.0 mm. The initiation condition of flooding in the latter case was also examined. Observed phenomena were auite similar to those in previous air-water experiments.
