Experimental Investigation on Two-Phase Flow Distribution in Multi-Channel Manifold With Two Radial Inlets

An experimental investigation was conducted to study the two-phase flow distributions in a horizontal cylindrical manifold with two radial inlets and 11 parallel channels. The effects of the different inlet conditions on two-phase flow distribution of parallel channels in the manifold were investigated. The flow rates of air and water in 11 channels were measured under symmetrical and unsymmetrical inlet conditions. Experimental results show that the air and water flow distributions of manifold at channels keep a stable flow ratio when two radial inlet conditions keep symmetrical. Water flow distribution has a significant variation and air flow distribution has a small change when two radial inlet conditions keep unsymmetrical and water superficial velocity increases at right inlet. Water and air flow distribution has a significant variation when two radial inlet conditions keep unsymmetrical and air superficial velocity decreases.
