Slug flow behavior in a hilly terrain pipeline
TLDR
In this paper, a slug-tracking model is proposed that follows the behavior of all individual slugs and is capable of simulating the aforementioned processes in a hilly terrain pipeline, where slugs can be generated at low elbows, dissipate at top elbows and shrink or grow in length as they travel along the pipe.About:

On the simulation of three-phase slug flow in nearly horizontal pipes using the multi-fluid model
M. Bonizzi,R. I. Issa +1 more
TL;DR: In this paper, a mathematical model to simulate three-phase (liquid/liquid/gas) stratified and slug flows is presented, based on the one-dimensional transient two-fluid model in which the two-phases consist of the gas and the mixture of the two liquids, with the motion of the liquid phases relative to each other being modelled via a drift-flux model.

Effect of gas compressibility on a slug tracking model
Yehuda Taitel,Dvora Barnea +1 more
TL;DR: In this article, the effect of gas compressibility on the slug length evolution and inlet pressure is computed, and some initial results and numerical approaches are discussed. But the results are limited to the case where the gas compressible is neglected.

Modeling of two-phase slug flow
J. Fabre,Alain Liné +1 more
TL;DR: Slug flow is a class of intermittent flows that has very distinctive features Even if the inlet conditions are stationary, the flow as seen by an observer, is an unsteady phenomenon, dispersed flow appearing alternately with separated flow as mentioned in this paper.

Hydrodynamic model for gas‐liquid slug flow in vertical tubes
TL;DR: A series of equations based on the physical processes thought to take place during slug flow were developed in this paper to predict the hydrodynamic character of this complex flow pattern, which appeared to validate the model.
