Slug frequency is one of the most important parameters for designing industrial installations
where intermittent gas-liquid flows could be found. Thus, the literature is found full of various …

Slug flow is a dynamically complex two-phase flow pattern. A wide variety of industrial gas-
liquid systems operate under slug flow conditions for not only flow transportation purposes …

This work demonstrates the artificial neural network (ANN) ability for predicting slug liquid
holdup (H LS), using 2525 measured points from 20 experimental studies. Six variables …

Experiments of gas–liquid flow in a circular pipe for horizontal and inclined positions
(upward/downward) are reported. The characteristics of two-phase flow in terms of liquid …

In horizontal configuration, the gas-liquid intermittent flow can be plug flow or slug flow.
Different works have demonstrated that the two flow patterns, despite their similarity, are …

Slug liquid holdup, translational velocity, and slug length are representative slug
characteristics. The precise prediction of these parameters is essential for the accurate …

Mechanistic modeling is one of the most popular approaches for the prediction of flow
pattern, pressure gradient and liquid holdup in multiphase flow problems. Mechanistic …

Liquid holdup is one of the most significant parameters in multiphase flow. Accurate
measurement of liquid holdup is required to calculate pressure drops in oil and gas wells …

Several experimental studies have been conducted to investigate the effect of liquid
viscosity on slug frequency in horizontal, vertical, and inclined two‐phase flows. Analyses of …

Empirical correlations have been proposed for estimating slug liquid holdup, H LS, using
Froude number, N Fr, viscosity number, N μ, and inverse viscosity number, N f. Some of …
