Experimental Study of Phase Separation in Dividing Two Phase Flow

Abstract

Experimental study of phase separation of air-water two phase bubbly, slug flow in the horizontal T-junction is carried out, the influences of the inlet mass quality XI, mass extraction rate G3/G1, and fraction of extracted liquid QL3/QL1 on phase separation characteristics are analyzed. For the first time, we have found and defined “Pulsating run effect” by the visual experiments, which show that under certain conditions, the down stream flow of the T-junction has strangely affected the phase redistribution of junction, and firstly point out that the downstream geometric condition is very important to the study of phase separation phenomenon of two-phase flow in T-junction.
