Study on phase distribution in a miniature T-junction

Abstract

In this paper, experimental results on air‐water two‐phase flow in a miniature T‐junction with hydraulic diameter of 1 mm are presented. Both superficial water velocities and superficial air velocities are taken as 0.01∼0.03 m/s in the experiments, respectively. When superficial air velocities are taken as 0.01∼0.03 m/s and superficial water velocity is 0.02 m/s. It is found that superficial air velocities have little effect on phase distribution. When superficial water velocities are taken as 0.01∼0.03 m/s and superficial air velocity is 0.02 m/s, X3/X1 of the branch increases with increasing superficial water velocity. Slug flow is the only pattern observed in our working condition.
