TLDR
In this paper, the internal structure of different sub-regimes of slug flow is analyzed and five distinct slug flow subregimes are identified based on the visual observations, which correspond to slug at formation stage (onset of slug); less aerated slug; highly aerated slugs; slug and plug; and slug and wavy.About:

Characterization of slug flow in heavy oil and gas mixtures
TL;DR: The methodology proposed against the original was compared, from experimental data of upward slug flow in inclined pipes finding that with the optimization there is better performance when working at inclination angles close to the vertical, and suggests a combined use of both methods.

Modified Image Processing Technique for Measurement of Intermittent Flow Characteristics
TL;DR: In this paper , a modified image processing technique in MATLAB is used for accurate measurement of intermittent flow characteristics, such as slug/plug frequency, liquid plug length, liquid slug/slug length, and liquid plug/plug velocity.

A model for predicting flow regime transitions in horizontal and near horizontal gas-liquid flow
Yemada Taitel,A. E. Dukler +1 more
TL;DR: In this article, a generalized flow regime map based on this theory is presented, which is used for determining flow regime transitions in two-phase gas-liquid flow, and the mechanisms for transition are based on physical concepts and are fully predictive.

A flow pattern map for gas—liquid flow in horizontal pipes
TL;DR: Govier and Aziz as mentioned in this paper used flow pattern maps for two-phase gas-liquid flow in horizontal pipes and compared them with the 5935 flow pattern observations currently contained in the UC Multiphase Pipe Flow Data Bank.

The onset of slugging in horizontal stratified air-water flow
Graham B. Wallis,John E. Dodson +1 more
TL;DR: In this paper, a simple criterion for the transition from stratified flow to the slug or plug flow regime in horizontal rectangular ducts is presented and a theoretical model is developed and shown to be consistent with data obtained by blowing air over stationary water in channels with a wide range of geometrical parameters.
Journal ArticleDOI
Prediction of the initiation of slugs with linear stability theory
P.Y. Lin,Thomas J. Hanratty +1 more
TL;DR: In this paper, the authors explored the application of linear stability theory to explain the onset of slugging and showed that the inviscid Kelvin-Helmholtz theory correctly predicts stability of a stratified flow only for very large liquid viscosities.
