This paper provides a comprehensive review of published experimental and numerical works in horizontal pipes, including a critical analysis of state-of-the-art parameters used to characterize the slug flow regime. The discussed slug characteristics are slug length, slug frequency, and slug velocity. Throughout the paper, an endeavor does devote to discerning the areas where modern development work is needed. Accordingly, some observed gaps in the literature, comprising hydrodynamic behavior at the transition zone and the interaction between slug flow and structural pipe. The lack of comprehensive laboratory experimental information for high liquid viscosity and the viscosity impact on the slug characteristic is also observed. On the contrary, robust and less empirically independent CFD models are required for accurately predicting the slug characteristics with a minimal computational cost. © 2021 Elsevier Ltd date: 2021 publisher: Elsevier Ltd official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85103945213&doi=10.1016%2fj.ces.2021.116611&partnerID=40&md5=d54d5fbbbbaf4440dd02dd3d57d87930 id_number: 10.1016/j.ces.2021.116611 full_text_status: none publication: Chemical Engineering Science volume: 238 refereed: TRUE issn: 00092509 citation: Mohmmed, A.O. and Al-Kayiem, H.H. and Osman, A.B.
