“…The slug formation, slug propagation and slug holdup of gas-liquid two phase flow in a horizontal circular pipe was investigated. More recently, in [12] used VOF to conclude that the gas superficial velocity was significantly affected by the liquid plug holdup. They also found that gas slug length was higher than liquid slug length for all conditions.…”

“…They tried to improve all flow regimes from Baker chart by using CFD method. More recently, VOF method has been used by Deendarlianto et al (2016) to study air-water two-phase plug flow in the horizontal pipe with 0.026-m ID and 9.5-m length. They found that the gas superficial velocity was significantly affected to the liquid plug holdup, and it was fluctuated strongly with the time variation by increasing the superficial velocity of gas.…”

Purpose-The purpose of this paper is to investigate oil-gas slug formation in horizontal straight pipe and its associated pressure gradient, slug liquid holdup and slug frequency. Design/methodology/approach-The abrupt change in gas/liquid velocities, which causes transition of flow patterns, was analyzed using incompressible volume of fluid method to capture the dynamic gasliquid interface. The validity of present model and its methodology was validated using Baker's flow regime chart for 3.15 inches diameter horizontal pipe and with existing experimental data to ensure its correctness. Findings-The present paper proposes simplified correlations for liquid holdup and slug frequency by comparison with numerous existing models. The paper also identified correlations that can be used in operational oil and gas industry and several outlier models that may not be applicable. Research limitations/implications-The correlation may be limited to the range of material properties used in this paper. Practical implications-Numerically derived liquid holdup and holdup frequency agreed reasonably with the experimentally derived correlations. Social implications-The models could be used to design pipeline and piping systems for oil and gas production. Originality/value-The paper simulated all the seven flow regimes with superior results compared to existing methodology. New correlations derived numerically are compared to published experimental correlations to understand the difference between models.

“…Deendarlianto et al. 23 carried out the VOF model to understand the gas–liquid behavior of two-phase plug-flow pattern in a horizontal pipe with 26-mm pipe diameter. A comparison with high speed camera results had also done for flow structure of the gas slug nose and tail.…”

The horizontal bubbly two-phase flow is preferably used in various industrial applications because it provides high interfacial areas which enhance the heat and mass transfer. In the present research, the phase distribution of controlled air-water flow in a horizontal acrylic round pipe with 60 mm inside diameter (D) has been investigated experimentally and modeled numerically. The modeled differential pressure and the mixture velocity profile at a distance of 33D from the mixing section (fully developed region) are computed numerically and compared with those obtained experimentally from the two-phase flow system established and maintained at the National Institute of Standards (NIS-Egypt). Furthermore, the numerical and the experimental data have been compared with previous correlations and models. Reasonable quantitative agreement between all data is found. An electronic device based on Arduino Uno board was designed and used with careful data manipulation for measuring the slug bubble velocity. The results point out that the air volume fraction has a maximum value at the upper pipe wall as the gas bubbles tend to migrate to the upper wall. A new correlation was obtained for bubble migration length to the upper pipe wall which is very important in chemical industrial processes and other engineering application.
