Two-phase flow in horizontal impacting tee junctions: Current state of the art.

摘要

The present investigation presents a summary of the state of the art in our understanding of the phase distribution in horizontal impacting tee junctions during two-phase flow. The currently existing data base was reviewed and the effects of different parameters on the phase distribution were investigated. These parameters include J_L1, J_G1, P₁, x₁, inlet flow regime, and inlet momentum-flux ratio. It was found that there is a serious lack of pressure-drop data and high-inlet-quality phase-distribution data.; The effect of J_L1 was such that as J_L1 increases with J_G1 fixed, the line, or curve that represents the data rotates in a clockwise direction. It is demonstrated that none of the available models/correlations can provide accurate predictions of magnitude and trend for all inlet conditions. The design of a test facility that is capable of generating phase-distribution and pressure-drop data for low-pressure, air-water two-phase flow through an impacting tee junction is given.
