Paper Number: BHR-2016-191
... Abstract This paper presents a simplified model for gas-liquid two-phase flow in churn and annular flow regimes for small- and large-diameter near-vertical pipes. Churn flow is considered by many investigators as the least understood flow regime in upward gas-liquid flow in vertical pipes...

Paper Number: BHR-2012-A026
... ABSTRACT: In this paper results from experimental investigations on the behaviour and interaction of elongated air bubbles in water in a 254 mm diameter vertical pipe are presented. For the experiments three identical observation/measurement stations, each of them comprising a transparent...
