... flow is considered as a gas-liquid slug flow, where the liquid is a water-in-oil emulsion. Closure parameters for the model are thoroughly discussed and the model trend is validated against experimental results obtained in a flow loop. Mass and heat transfer limitation processes are discussed in terms...

... influences the dynamics of pipeline pressure, and liquid content and outlet rates; production rates span the region of transition between separated and slug flow regimes. Out-of-the-box model predictions of pressure drop can differ from measured values by 20% or more. While model predictions of liquid...

... ABSTRACT Slug flow continues to be a disruptive influence on both design and operation of multiphase pipelines and risers. In the past, the focus was largely on slugging cycles driven by the riser or driven by large scale terrain effects which were ultimately accommodated through slug catcher...

... flow and slug flow in vertical pipes. From a physical interpretation point of view, the coupling in the hybrid model is not problematic since the VOF model uses an indicator function for tracking the interface between the phases, which has the same meaning as a volume fraction variable in the two-fluid...

... and one dual wire mesh sensor. The experiments covered all the important flow regimes (bubbly flow, slug flow, churn flow and annular flow), yielding a unique and highly relevant data set with detailed measurements. The new data set, combined with data from previous vertical flow campaigns...

... Abstract This paper presents velocity measurements performed in hydrodynamic slug flow in a 212 m long horizontal pipe. A post-processing step has been developed to combine Laser Doppler Anemometry (LDA) measurements with liquid height measurements, such that it is possible to build (i) mean...

...-phase gas-oil flow (saturated oil, or with gas production, or gas-lift in well), oil-water flow (under-saturated oil) and three-phase oil-water flow. In situations with presence of gas and water in the flowline, the flow regime is dominated by three-phase slug flow. Many studies of three-phase slug flow...

... Capacitance Tomography (ECT). Results show that OLGA gave a good prediction of the measured pressure gradient however with decreasing capabilities as liquid viscosity increased. OLGA point model over predicted the slug flow pattern and under predicted the liquid holdup in this study. Introduction The oil...

A novel approach is presented which uses a quasi-three-dimensional (Q3D) CFD method to obtain horizontal slug flow inlet boundary conditions for subsequent force prediction...

... ABSTRACT Slug flow is one of the commonly encountered liquid and gas two-phase flow patterns. The accurate prediction of its behaviours is crucial for practical engineering applications. Liquid viscosity and pipe diameter are found to have significant impacts on slug frequency, but available...
