- Abstract
• CFD models are developed for core annular flow through 90° elbow. • The simulation model has been verified by experimental and empirical values. • The effects of inlet water fraction, the oil-water property and the geometrical parameters on hydrodynamic performance are predicted. • The results could provide a reference for the design of 90° elbow structures and the optimization of flow parameters. The transportation of heavy oil surrounded by water annular can significantly reduce the resistance and reduce energy consumption. In the process of conveying high viscosity oil, it will inevitably pass through elbow components. In the present study, the stability in the development of core annular flow (CAF) by the influence of the elbow was investigated by computational fluid dynamics (CFD). The simulated data matched well with the previous experimental data and empirical correlation, which indicates the reliability and practicability of the model. The effects of inlet water fraction, the oil-water property (density ratio, viscosity ratio), and the geometric parameters (diameter ratio, curvature ratio) on hydrodynamic performance, eccentricity and oil transportation efficiency were analyzed, and the results could provide a reference for the design of 90° elbow structures and the optimization of flow parameters.
