“…Given the recent progress made in mapping the horizontal flow pattern by Osundare et al (2022) and Korelstein and Pereyra (2023), the results obtained raises the idea of using a separate coordinate system for the different flow transition for this pipe configuration, as suggested by Taitel and Dukler (1976). Future work, using larger pipe diameters, is strongly encouraged to confirm/correct the proposed sub-regimes transitions.…”

“…Meanwhile, this statement is not valid for the LAS-to-HAS flows transitions. This coordinate system was recently suggested as the most suitable one for the prediction of flow transition in horizontal configuration by recent studies of Osundare et al (2022) and Korelstein and Pereyra (2023).…”

These recent years, several experimental investigations were carried out on horizontal gas-liquid two-phase sub-regimes including plug, Less Aerated Slug (LAS) and Highly Aerated Slug (HAS) flows. Such classification is based on the shape of the elongated bubble/liquid slug interface as well as the aeration in the liquid slugs. In this paper, an extensive experimental visualization was performed using air-water mixture in a 30 mm ID horizontal pipe covering a total of 189 operating conditions. It was reported, for the first time, that each sub-regime had a specific mechanism of aeration of the liquid slug flow. For instance, the presence of gas bubbles within liquid slugs, in case of plug flow, is due to the interfacial shear induced waves mechanism. The transitions to LAS and HAS flows are accompanied by the appearance of shearing-off and scooping mechanisms of bubbles, in the liquid film, into the liquid slug, respectively. In addition, the reported flow transition lines, as well as those existing in the literature, were analyzed using different existing coordinate systems. This analysis showed that the X-T system is the most suitable for predicting the three flow sub-regimes.

“…According to the authors, this flow map has the advantage of being scalable to different pipe diameters and pressures, compared with that of Mandhane et al (1974). Osundare et al (2022) have also reported the possibility of using the Froude number of the individual phases as coordinates.…”
