Tittel

Flow structures of gas-liquid slug flow in annuli using X−ray tomography

Sammendrag

In this work, an X-ray system consisting of six cameras was used to obtain instantaneous cross-sectional phase distribution of gas-liquid flow in annuli. The horizontal annulus test section, made of PVC, consisted of an outer pipe of 99 mm inside diameter and an inner pipe of 50 mm outside diameter using two different configurations, namely, concentric and fully eccentric (with the inner pipe at the bottom of the outer pipe). The test fluids used in this investigation were water and a low viscosity oil (Exxsol D60) as the liquid phases and sulphur hexafluoride (SF6) as the gas phase. Results reveal that flows in the presence of a fully eccentric annulus have a more consistent behaviour in terms of phase distribution. Three-dimensional flow structures were reconstructed based on the instantaneous cross-sectional phase distribution. This offers insight into the Taylor bubble nose and tail shape as well as the evolution of the liquid film.
