Experimental investigation of the flow characteristics of two phase current in a manifold

The variations in the exit flow rates and behaviors at five outlet ports opened on the manifold pipe system, through which a flow of water and air-water (two-phase) mixtures passes horizontally, have been experimentally investigated. The effect of different air flow rates vacuumed from the atmosphere with the aid of a venturi device installed in the system on the exit flow rates and diameters of manifold port exits has been compared with measurements of exit jet lengths. The system performance ensuring the homogeneity of manifold port exit flows has been tested. As a result, it has been observed that homogeneous jet lengths are obtained at both single and two-phase low main manifold flows and with equal exit port diameters. When the main manifold flow velocity V is 1.5-2 m/s, the system is stable and produces high jet lengths. Additionally, it provides suitable operating conditions for d/D=0.433.
