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:

Effect of Forced Flow Oscillation on Churn and Annular Flow in Vertical Wellbores
TL;DR: In this paper, the authors investigated the influence of multiphase flow on pressure gradient in VERTICAL PIPE under various conditions and found that the relationship between Multiphase Flow Correlations to Predict Pressure Gradient and Oscillation Conditions in Pipes was investigated.

Influence of Horizontal Pipe Length to Flooding of Counter Current of Water-Air Flow in Complex Pipe
TL;DR: In this paper, the effect of horizontal pipe length on flooding phenomenon was studied using a hot leg simulator, which consisted of an acrylic horizontal pipe with inside diameter of 25.4 mm and an elbow with inclination angle of 50 0.

On axial coherence of interfacial waves in countercurrent flow
TL;DR: In this article, the authors measured the instantaneous wall shear stress using an electrochemical method just below the liquid feed, as well as just above the liquid withdrawal point, and found that in all instances of countercurrent flow, including conditions along the flooding curve, the time-averaged wall stress was directed upward indicating that the velocity near the wall was downward.

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.

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.
