Studies of the pressure drop and mass flow distribution of two-phase flow in rectangular T-junctions

The aim is to work out the principles governing the redistribution of two-phase flows in T-junctions. This has been achieved by carrying out studies in an air-water flow on T-pieces of identical diameter exposed to a horizontal inflow but with the branching pipes inclined in different directions. The mass flow, the gas content of the inflow and the differential pressures over the T-junction were varied over wide ranges, in order to cover a substantial spectrum of phase and velocity distributions (type of flow). During these studies the mass flow and gas content values were determined in the branch pipe and in the outflow and the pressure distribution measured over the length of the pipe axis. The influence of the system pressure on the phase redistribution has been examined for a horizontal branching layout in a stream/water flow for pressures not exceeding 10 MPa.
