The main goal of this work is to analyze the efficiency of a two-phase flow distribution system for different operational conditions, which was designed and built by the Multiphase Flow Research Center (NUEM). The distribution system is composed of a two tangential inlets, a cyclonic chamber, and four outlets. The working principle of this apparatus is based on the combined action of centrifugal and gravitational forces, which causes the development of a liquid film, facilitating the flow distribution. Four outlets are located perpendicularly to the cyclonic chamber in order to distribute the flow equally to some extent. Experimental tests were performed using water and air in a vertical 52-mm ID acrylic pipe. Two flow patterns (bubble and slug) at the input of the inlets were visually identified through the use of a high-speed camera. To verify the flow distribution, wire-mesh sensors were installed at each outlet and graduated beakers and a timer was used in order to estimate the liquid volume flowing at the outlets. The results showed that the flow distribution system has a satisfactory efficiency of distribution.
