FLOW OBSERVATION AND DISTRIBUTION OFTWO-PHASE FLOW IN A DISTRIBUTOR

摘要

In order to understand flow configurations and distribution behavior of gas and liquid two-phase flow inrndistributors, a basic experiment has been carried out for a two-path distributor by using air and water twophasernflow as working fluids. The two-path distributor was arranged so that one of the paths wasrndownward and another was upward. Both the branches are parallel with each other and they have thernsame direction as the main channel. The inclination angle of the distributor was changed as horizontal,rn30o and 60o. A fully developed air-water two-phase flow enters the main channel and is separated into thernbranches. The flow is upward when the distributor is inclined. Flow patterns in the main channel werernstratified, slug, and annular according to the flow rates of air and water. Flow configurations during thernseparation were observed by a high-speed camera and effects of gravity and entrance flow pattern wererninvestigated.
