Non-linear interfacial instability of separated flow
Dvora Barnea,Yehuda Taitel +1 more
TLDR
In this paper, the evolution of finite disturbances is studied by numerical simulations of the wave growth or decay using the method of characteristics, and three basic behaviors are identified: (1) the waves decay with time; (2) the wave amplitude grows until conditions of ill posedness at the wave crest is achieved and (3) the shape of wave is distorted and develops steep slopes that lead to wave break.About:

Slug initiation and evolution in two-phase horizontal flow
TL;DR: In this article, a series of two-phase air-water experiments was carried out in order to study the initiation and the subsequent evolution of hydrodynamic slugs in a horizontal pipeline.

Interfacial and structural stability of separated flow
Dvora Barnea,Yehuda Taitel +1 more
TL;DR: In this article, the stability of separated flows is discussed using two approaches: the interfacial stability analysis and the structural stability analysis, using linear and non-linear analyses, respectively.

Transition between stratified and non-stratified horizontal oil–water flows. Part I: Stability analysis
TL;DR: In this article, the wave characteristics at the interface of oil-water stratified flow and at the onset of entrainment, where drops of one phase appear into the other, were studied.
Journal ArticleDOI
Flow regime independent, high resolution multi-field modelling of near-horizontal gas-liquid flows in pipelines
TL;DR: In this paper, the development of flow regimes and various flow parameters without the need for maps, or the need to change closure relationships is predicted without requiring flow regime maps and closure relationships that depend on them.

The role of interfacial shear modelling in predicting the stability of stratified two-phase flow
Neima Brauner,David Moalem Maron +1 more
TL;DR: In this article, the authors proposed a new form for interfacial shear, which incorporates an explicit functional dependence on the interface slope due to interfacial waviness, and the implementation of the proposed model as a closure law in the stability analysis of stratified flows reveals the crucial role of the dynamic term in determining the stability characteristics.

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.

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.
