Visualization the Distribution of Air-Water Mixtures Flow in Two Outlet Distributor

Abstract

This study presents an experimental investigation of air-water mixture distribution (gas and liquid phase) in a distributor. The distributor with one inlet and two outlet tubes branch, upper part and lower part is used with the aim that flow through it can be distributed evenly, particularly in two phase flow. The flow distribution was observed by a high-speed video camera and volumetric flow rates of air and water were measured for each outlet branches, respectively. Inclination angle effect of the distributor and flow rate of air and water flow pattern were investigated. It was found that through distributor, evenly distribution will occurs by the superficial velocity gas and liquid in large quantity. Water tends to flow out at the bottom, and air tends to flow out at the top of tube branch because effect of gravity and different fluid density. The distribution of two-phase flow through distributors tend unevenly flow distribution on the decrease of the angle of distributor, from vertical position to horizontal position.
