摘要

根据细长气泡/液态蛞蝓界面的形状和液态蛞蝓的曝气情况,水平间歇流可分为三种子形态,包括塞流(PG)、少曝气蛞蝓流(LAS)和高曝气蛞蝓流(HAS)。这些流动亚状态是在使用空气-水混合物和小管径进行的实验中观察到的。本文对所获得的结果进行了分析,目的是对这一子规程分类的最新进展进行总结。通过对当前知识水平的批判性回顾,我们得出结论:将间歇流细分为子规程,可以更好地理解、认识和推进弹头参数建模、界面区浓度、管道完整性管理、跨越奇点的间歇流行为,以及开发更逼真的力学模型。所获得的知识可用于石油和天然气、核能和化学工程等行业。最后,根据所介绍的最新技术,为今后使用这种方法开展工作提出了一些建议。这些反射路径将有助于提高我们对间歇流的理解,促进开发更强大的模型。

Sub-regimes of horizontal gas–liquid intermittent flow: State-of-the-art and future challenges

Based on the shape of the interface elongated bubble/liquid slugs and the liquid slugs’ aeration, the horizontal intermittent flow can be divided into three sub-regimes including plug (PG), Less Aerated Slug (LAS) and Highly Aerated Slug (HAS) flows. These flow sub-regimes were observed from experiments performed using air–water mixture and small pipe diameters. This paper presents an analysis of the results obtained with the aim of constituting the state-of-the-art of this sub-regimes classification.

The critical review, of the current state of knowledge, has led to the conclusion that the subdivision of intermittent flow into sub-regimes may provide a better means of apprehending, understanding and advancing in the modelling of slug parameters, Interfacial Area Concentration, Pipeline Integrity Management, intermittent flow behavior across singularities, as well as for the development of more realistic mechanistic models. The acquired knowledge can be beneficial for petroleum and gas, nuclear and chemical engineering industries among others.

Finally, based on the presented state-of-the art, some recommendations are given for future works using this approach. These reflection paths will allow improving our comprehension on intermittent flow, promoting the development of more robust models.

期刊介绍: Experimental Thermal and Fluid Science provides a forum for research emphasizing experimental work that enhances fundamental understanding of heat transfer, thermodynamics, and fluid mechanics. In addition to the principal areas of research, the journal covers research results in related fields, including combined heat and mass transfer, flows with phase transition, micro- and nano-scale systems, multiphase flow, combustion, radiative transfer, porous media, cryogenics, turbulence, and novel experimental techniques.
