Phase‐Split in Two‐Phase Flow through T‐Junction

Abstract

A numerical investigation is made on the Phase-split phenomena in liquid-liquid two- phase flow through T-junction. The phenomena are studied by varying the fluid-pair, branch position, diameter of the pipe and the angle between the branch and run. For better understanding, both horizontal and vertical T-junction arrangements are considered in the present case. To simulate the problem, Finite Volume Method (FVM) with 3D Volume of Fluid (VOF) model have been used. The results are shown in terms of phase-contour in the mid plane, variation of volume fraction along the length of the individual pipe and the distribution of phase in several cross-section. There is a difference in the phase variation along the run and branch. This difference is more prominent in vertical T-Junction compare to that in the horizontal T-Junction. The volume fraction of the oil is always decreasing along the branch and run, and it is irrespective of the vertical and horizontal arrangement. But volume fraction almost remain constant along the inlet section in the horizontal T-junction and increases along the inlet section in the vertical T-junction.
