TLDR
In this paper, the wave deformation limit and the most dangerous wave concept were introduced in the stability analysis of a slug flow in a horizontal duct, and a potential flow analysis was carried out by considering waves of finite amplitude.Abstract:
A criterion for the onset of a slug flow in a horizontal duct is derived theoretically. A potential flow analysis is carried out by considering waves of finite amplitude. The stability criterion is obtained by introducing the wave deformation limit and the “most dangerous wave” concept in the stability analysis. The present theoretical criterion for slug formation shows very good agreement with a large number of experimental data and with some empirical correlations.read more

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.

Viscous potential flow analysis of Kelvin–Helmholtz instability in a channel
Toshio Funada,Daniel D. Joseph +1 more
TL;DR: In this article, the stability of stratified gas-liquid flow in a horizontal rectangular channel using viscous potential flow was analyzed and a dispersion relation was established, in which the effects of surface tension and viscosity on the normal stress are not neglected but the effect of shear stresses is.
