TLDR
In this article, the effect of tube diameter on the mechanism of flooding in vertical gas-liquid countercurrent annular flow was investigated. But the results indicated that the mechanism was qualitatively different in the small and the large diameter test sections.About:

Flooding behaviour in countercurrent gas-liquid flow in vertical tubes with turbulence promoters
TL;DR: In this paper, a test apparatus was built up to study the flooding behavior of a countercurrent adiabatic air-water two-phase flow in a vertical glass tube.

Semi-empirical correlation for counter-current flow limitation at the upper or lower end of sharp-edged vertical pipes
TL;DR: In this article, a semi-empirical correlation for countercurrent flow limitation in vertical pipes was derived from one-dimensional momentum equations, and the fundamental functional form of the correlation was also transformed to express the characteristics of CCFL occurring at the sharp-edged upper end of a vertical pipe.

TL;DR: In this paper, the effects of condensation and tube inclination on flooding in large diameter tubes were investigated and a semi-empirical correlation for the onset of flooding was found.

An experimental study on gas–liquid two-phase countercurrent flow limitations of vertical pipes
TL;DR: In this article , the effects of pipe diameter and pipe length on the countercurrent flow limitation (CCFL) of vertical pipes were determined by experimentally analyzing the gas-liquid two-phase CCFL in vertical pipes.

Prediction of the slug-to-churn flow transition in vertical two-phase flow
TL;DR: In this paper, an assessment of the various viewpoints on the slug-to-churn flow transition in vertical upward flow in the light of recent experimental results obtained at Harwell Laboratory is made.
Journal ArticleDOI
Flooding in tubes and annuli
TL;DR: In this article, a new flooding correlation is presented which solves the obvious contradiction between the Wallis correlation and the study by Pushkina and Sorokin concerning the scaling question at zero penetration of liquid.

A critical review of the flooding literature
S. George Bankoff,Sang Chun Lee +1 more
TL;DR: In the absence of electromagnetic force fields, thermocapillary effects or concentration-capillary effects, countercurrent flow can be sustained only as a result of the difference in the gravitational force per unit volume on the gas and on the liquid as discussed by the authors.

Air-water countercurrent annular flow
D. Bharathan,Graham B. Wallis +1 more
TL;DR: In this paper, the authors investigated the effect of tube end geometries on measured countercurrent fluxes, liquid fraction, and pressure gradients, and analogies between countercurrent gas-liquid flow and other more familiar flows in internal geometry are indicated.

Flooding and churn flow in vertical pipes
TL;DR: In this paper, a 32 mm dia vertical pipe with various forms of liquid outlet, namely a porous wall, a tapered outlet, and a square-edged outlet, was used to investigate the effect of churn flow on the penetration rate.
