Analysis, Comparison, and Discussion on the Utilization of the Existing Slug Liquid Holdup Models to Predict the Horizontal Gas-Liquid Plug-to-Slug Flow Transition
Autor: Ayoub Boutaghane, Abderraouf Arabi, Nouara Ibrahim-Rassoul, Abdelsalam Al-sarkhi, Abdelwahid Azzi
Publikováno v: Journal of Energy Resources Technology. 145
In horizontal configuration, the gas-liquid intermittent flow can be plug flow or slug flow. Different works have demonstrated that the two flow patterns, despite their similarity, are differents. Thus, it is important to differentiate between them i

Publikováno v: SPE Journal. 27:1577-1596
SummaryThe intermittent gas-liquid flow can be seen in both vertical upward and horizontal pipes. In a vertical pipe, the gas pockets of intermittent flow can be present as cap bubbles (cap bubble flow) or Taylor bubbles (slug flow), while in a horiz

Pressure recovery model for gas-liquid two-phase flow across sudden expansions
Autor: Abderraouf Arabi, Ghassan H. Abdul-Majeed, Houari B. Boukrouche, Zakaria Larbi
The presence of a sudden expansion generates a variation of the static pressure commonly called Pressure Recovery (PR). In this paper, we made firstly an extensive literature survey to list existing gas-liquid two-phase flow pressure recovery models

Empirical Correlations for Prediction Slug Liquid Holdup on Slug-Pseudo-Slug and Slug-Churn Transitions in Vertical and Inclined Two-Phase Flow
Autor: Ghassan H. Abdul-Majeed, Abderraouf Arabi, Gabriel Soto-Cortes
Publikováno v: SPE Production & Operations. 36:721-733
SummaryMost of the existing slug (SL) to churn (CH) or SL to pseudo-slug (PS) transition models (empirical and mechanistic) account for the effect of the SL liquid holdup (HLS). For simplicity, some of these models assume a constant value of HLS in S

Empirical Modelization of Intermittent Gas/Liquid Flow Hydrodynamic Parameters: The Importance of Distinguishing between Plug and Slug Flows
Autor: Buddhika N. Hewakandamby, Rabah Kadi, Abdelwahid Azzi, Abderraouf Arabi, Abdelsalam Al-Sarkhi
Publikováno v: SPE Production & Operations. 36:703-720
SummaryIntermittent flow is one of the most complex flow regimes in horizontal pipes. Various studies have classified this regime as two distinct subregimes: plug and slug flow. This classification has been made based on flow observations. In this wo
