Few previous studies have considered gas�liquid slug flow and the associated fluid�structure interaction problems. In this study, experimental and numerical techniques were adopted to simulate and analyze the two-phase slug flow and the associated stresses in the pipe structure. In the numerical simulation, a one-way coupled fluid�structure framework was developed to explore the slug flow interaction with a horizontal pipe assembly under various superficial gas and liquid velocities. A modified Volume of Fluid and finite element methods were utilized to model the fluid and structure domains. The file-based coupling technique was adopted to execute the coupling mechanism. By contrast, slug characteristics were measured experimentally, while Bi-axial strain gauges were used to capture time-varying strain signals. Excellent agreements between the predicted and measured stress results were achieved with a maximum error of 10.2 . It was found that at constant superficial liquid velocity, the maximum induced stresses on the pipe wall increased with increasing the slug length and slug velocity. While for the slug frequency, the maximum principal stresses decreased with increasing the slug frequency. © 2020 Elsevier Ltd date: 2020 publisher: Academic Press official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85086824624&doi=10.1016%2fj.jfluidstructs.2020.103083&partnerID=40&md5=31009cd689ad53114d71144f958ee762 id_number: 10.1016/j.jfluidstructs.2020.103083 full_text_status: none publication: Journal of Fluids and Structures volume: 97 refereed: TRUE issn: 08899746 citation: Mohmmed, A.O. and Al-Kayiem, H.H. and Osman, A.B. and Sabir, O.
