Two-phase gas-liquid flow through Y-junctions

An investigation has been made of air-water flow in Y-junctions, which are frequently used in industrial applications. The air-water flow is stratified in the sloping limbs approaching the junction and this paper examines the phenomena occurring at the junction and in the following freely dischargin...

Description
Summary:An investigation has been made of air-water flow in Y-junctions, which are frequently used in industrial applications. The air-water flow is stratified in the sloping limbs approaching the junction and this paper examines the phenomena occurring at the junction and in the following freely discharging vertical pipe. It is shown that three flow regimes can exist in the vertical limb following the junction: freely-falling water, homogeneous flow of water and air, and flow of water with a small amount of residual air accompanied by the flooding of the junction. The flow regimes are described and predictions for transitions between them are developed.
