“…This is in agreement with the findings of [23], [39] and [42]. Figure 16 compares the present data against values predicted by correlations proposed by Gregory and Scott [5], [13] and [18]. It is seen that there is better agreement between present experimental data and the correlation of [5] as shown in the figure.…”

“…Gomez et al [13] analysed the data collated from the results of experimental studies conducted by a number of investigators who considered slug flows within pipes with internal diameters of between 51 to 203 mm, set at inclinations of between 0 -90 o , and operating at pressures of between 1.5 to 20 bar. This analysis identified a clear dependency between the angle of the pipe inclination, the slug Reynolds number (Re), and the slug void fraction.…”

Abstract:Despite the research efforts in the last decades, the dynamic behaviour of gas-liquid two-phase flows remains a challenging topic. This is due to the growing demand within the petroleum, process and nuclear industries. In particular, data on the behaviour of these flows in more industry relevant fluids are limited. This paper presents a summary of the experimental results on the hydrodynamic behaviour of slug flow using airsilicone oil mixture in a horizontal 67 mm internal diameter pipeline. A series of slug flow regime experiments were performed for a range of injected air superficial velocities (0.29 to 1.4 ms -1 ) and the liquid flows with superficial velocities of between 0.05 to 0.47 ms -1 . The translational Taylor bubble velocity and slug frequency were measured using two pairs of Electrical Capacitance Tomography (ECT) probes. The expected linear dependence of the translational Taylor bubble velocity on the mixture superficial velocity was confirmed.Pressure drop was measured using a differential pressure (dp) transducer cell. The void fractions in the liquid slugs and Taylor bubbles and slug and Taylor bubble lengths parameters were obtained from the processed data.The average total lengths of the observed slugs were of the order of 8 to 46 pipe diameters. The dimensionless Taylor bubble length is concluded to increase as the gas superficial velocity increases. The average slug frequency was observed to increase as the liquid superficial velocity increases but on the other hand was concluded to be fairly weakly dependent on the gas superficial velocity. The measured translational Taylor bubble velocities, void fractions in the liquid, and slug frequencies are presented and compared to data predicted by empirical models available in the literature. A comparative analysis of this and the previously published experimental data sets confirms good agreement.Key words: ECT, Taylor bubble, liquid slug, slug unit, frequency, void fraction 2 | P a g e Introduction:The determination of the multiphase flow regimes that may exist within pipelines is a key factor to the development of efficient oil and gas production systems. As oil and gas reserves are being depleted in developed fields, activity is shifting to harsher and less accessible environments. As offshore production moves into deeper waters farther offshore, the cost of constructing and operating fixed platforms with separation facilities becomes increasingly challenging. An alternative solution is to utilize subsea production systems which entail minimum offshore processing. The adoption of this method requires the simultaneous transport of produced fluids to land-based separation facilities, with minimal offshore treatment to reduce the undesirable effects as corrosion, wax and hydrates formation. Thus, an accurate prediction of the multiphase flow characteristics that may be experienced within these pipelines is therefore required to effect the safe and economic design and operation of these transportation systems.Slug flows are the most preva...

“…The technique allows a local determination of the various liquid holdups as well as of the capillary height, without dismantling the elements. Gomez et al (2000) developed a new dimensionless correlation for the liquid holdup in the slug body. The correlation incorporates the mixture velocity, liquid viscosity, pipe diameter and inclination angle.…”

“…There are only few studies related to liquid holdup prediction theoretically, experimentally or numerically (Wang et al, 2006;Xio et al, 2000;De Andrade Lima, 2006;Yin et al, 2002;Muzen and Cassanello, 2005;Van Hasselt et al, 1999;Bruce et al, 2004;Inglezakis et al, 2001;Afreka et al, 2007;Gomez et al, 2000;Ayude et al, 2007;Iliuta et al, 2002;Lopes and Quinta-Ferreira, in press;Rathess and Kannan, 2004;Atta et al, 2007). Wang et al (2006) measured phase distribution of solid particles, and oil droplets were conducted in a lab-scale stirred tank by sample withdrawal under various operating conditions.…”

-The maximum volume of liquid bridge left between two vertically mounted spherical particles has been theoretically determined and experimentally measured. As the gravitational effect has not been neglected in the theoretical model, the liquid interface profile is nonsymmetrical around the X-axis. Symmetry in the interface profile only occurs when either the particle size ratio or the gravitational force becomes zero. In this paper, some equations are derived as a function of the spheres' sizes, gap width, liquid density, surface tension and body force ( gravity/centrifugal) to estimate the maximum amount of liquid that can be held between the two solid spheres. Then a comparison is made between the result based on these equations and several experimental results.
