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 …

Two-phase flow is common in many industrial applications, especially in oil–gas production
and transportation. Identifying the configuration of the phases along the flow is extremely …

The accurate prediction of slug frequency is critical for the construction of multiphase flow
models and the flow assurance of oil and gas pipelines. In this paper, the slug frequency …

From wells to refining plants and distribution networks, operations in the oil and gas industry
involve the transport of multiphase mixtures through long pipelines. One of the most …

Large vertical pipes are key structures connecting subsea wells to offshore platforms.
However, existing studies mainly focus on small vertical pipes. In a vertical acrylic pipe with …

This study aims to understand the comprehensive behavior of the gas–liquid flow and
dissolution–evolution mass transfer. A quasi-static closed-tank experiment was designed to …

Accurate measurement and prediction of the intermittent flow characteristics in horizontal
pipes is important for constructing multiphase flow models and ensuring pipe flow safety. In …

Slug flow is present in many industrial processes, including the ones related to the
petroleum industry. Such flow pattern is characterized by the periodic passage of liquid …

Visualization experiments were often used to observe the flow patterns of gas-liquid two-
phase flow. The development of high-speed camera technology in recent years induces an …

The slug frequency (SF), which refers to the number of liquid slugs passing through a pipe
during a specific time, is an important parameter for characterizing the multiphase …
