Data on a semicircle cross-section header of 1.22 mm hydraulic diameter and three T-junctions with the corresponding side arms of 0.61 mm hydraulic diameter are presented. The gas and liquid superficial velocity ranges were 0.02-40.0 and 0.08-6.0 m/s. The following discernible flow regimes were considered: bubbly, bubbly to slug, slug, semi-annular, and churn flow. There are systematic trends on phase separation that depend on flow regime and on the T-junction location. %8 2010-06-29
