The segregated flow pattern, which occurs in a 26.1 mm diameter, horizontal, stainless steel test section,is investigated. Pressure gradient and in situ phase distribution data were obtained for different combinations of system (E0D=4.77), the dominant effect of interracial tension and wall-wetting properties of the liquids over the gravity is considered. The approach introduces the closure relationship for the case of turbulent flow in a rough pipe,and attempts to modify the two-fluid model to account for the curved interface. In present flow rates range, wave amplitudes were found small, while interfacial mixing was observed. An adjustable definition for hydraulic diame-ters of two fluids and interfacial friction factor is adopted. The predicted pressure gradient and in situ phase distri-bution data have been compared with present experimental data and those reported in the literature.
