Краткое описание

The flow distribution of air and water among the parallel vertical tubes of a manifold system was studied over a wide range of air and water flow rates. 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.
