本文介绍了一项关于气液流经悬链式管道立管时发展的研究的初步结果，该管道类似于石油和天然气工业中使用的立管。商业的一维多相流软件(PETEXGAP)被用来确定两个测试点的范围，这两个测试点代表了在这样的系统中可能出现的流型。使用StarCCM+计算的计算流体力学进一步探索了这些测试点。在这两个测试点，观测到立管的坡度加速了开尔文-亥姆霍兹波的开始。根据流速的不同，这些波动可以导致一些有趣的流动现象，如晃动的开始和弹状流的发生和消散。探讨了这些影响的潜在破坏性，特别是对使用柔性立管的实验以及这种形式的工业管道的影响。
This paper presents the initial findings of a study into the development of gas-liquid flows as they pass through a catenary-style pipeline riser, similar to those utilised in the oil and gas industry. A commercial, one-dimensional multiphase flow software (PETEXGAP) is used to scope two test points that represent flow regimes that are likely to occur in such a system. These test points are explored further using computational fluid dynamics, calculated using StarCCM+. In both test points, the gradient of the riser is observed to accelerate the onset of Kelvin-Helmholtz waves. Depending on the flow rates, these waves can lead to several interesting flow phenomena, such as the initiation of sloshing and the occurrence and dissipation of slug flow. The potentially destructive nature of these effects is explored, particularly in terms of the implications for experiments using flexible risers, as well as industrial pipelines of this form.
