T-junction is broadly utilized for phase separation, as it has a notable function as a conduit to distribute fluid, due to its simple design, low maintenance cost and adaptability to offshore industries. The geometrical parameters that influence phase separation make the phase re-distribution unpredictable. Even though the diameter ratio of the T-junction has a prominent effect on phase separation, it was not thoroughly and comprehensively reviewed specifically. This review article intends to fill in that gap, focusing solely on the effect of the diameter ratio on phase separation, specifically for two-phase flow in branching T-junction. Initially, the inversely proportional relation between diameter ratio and phase separation is discussed, reported first in the 1970s. Besides, a critical analysis in 1998, is reported which challenged the inverse proportionality. Unfortunately, their disagreement was not addressed for more than a decade. Lastly, two different criteria to determine the separation efficiency, state-of-the-art T-junction design and side arm modifications are summed up with conclusions. The primary contribution of this research is that it takes into account the agreement and disagreements among the researchers for inverse proportionality between phase separation and diameter ratio, including some critical findings that were not reported in the past in review articles. Some recommendations for future research in this domain are also reported.

综述:分支 T 型接头几何形状在直径比方面的演变,以改善相分离

T 型接头广泛用于相分离,因为它具有显着的分配流体管道的功能,因为其设计简单、维护成本低且适用于海上工业。影响相分离的几何参数使相重新分布不可预测。尽管 T 型接头的直径比对相分离具有显着影响,但并未对其进行彻底和全面的具体审查。这篇评论文章旨在填补这一空白,仅关注直径比对相分离的影响,特别是对于分支 T 型接头中的两相流。最初,讨论了直径比和相分离之间的成反比关系,最早是在 1970 年代报道的。此外,1998 年的一项批判性分析,据报道,这对反比例性提出了挑战。不幸的是,十多年来,他们的分歧没有得到解决。最后,对确定分离效率的两个不同标准、最先进的 T 型接头设计和侧臂修改进行了总结并得出结论。这项研究的主要贡献在于,它考虑了研究人员之间关于相分离和直径比之间成反比的共识和分歧,包括过去在评论文章中没有报道的一些关键发现。还报告了对该领域未来研究的一些建议。总结了最先进的 T 型接头设计和侧臂修改并得出结论。这项研究的主要贡献在于,它考虑了研究人员之间关于相分离和直径比之间成反比的共识和分歧,包括过去在评论文章中没有报道的一些关键发现。还报告了对该领域未来研究的一些建议。总结了最先进的 T 型接头设计和侧臂修改并得出结论。这项研究的主要贡献在于,它考虑了研究人员之间关于相分离和直径比之间成反比的共识和分歧,包括过去在评论文章中没有报道的一些关键发现。还报告了对该领域未来研究的一些建议。
