Abstract: In the present work the investigation of gas and liquid slugs for Taylor flow in curved tubes has been carried out numerically using CFD. In case of curved tubes due to the curvature the flow is 3D, therefore 2D geometry can not be used to predict the slug flow development. The 3D models for curved tube with premixed feed is considered for the slug flow development study. The Volume of fluid (VOF) is used to capture the interface between gas and liquid slugs, which is an implicit free surface reconstruction method. The development of the gas and liquid slugs in the model geometry at various operating and fluid conditions is investigated. The phenomenon of flow reversal and slug freezing is observed in the curved tube. It is also observed that the viscosity, surface tension and wall surface adhesion moderately impact the slug development.
