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 Performance of Square Channel Monolith Structures
TL;DR: The performance of square channel monoliths for a wide range of geometric parameters and liquid properties has been evaluated in this article, showing that the column diameter has a rather negligible effect on flooding.

Theoretical prediction of flooding velocity in an inclined tube based on viscous Kelvin-Helmholtz instability
TL;DR: In this paper, the authors performed the viscous Kelvin-Helmholtz instability analysis with a simplified one-dimensional model and found that surface tension acts as a stabilizing force and cannot be ignored.

Water inlet subcooling effects on flooding with steam and water in a large diameter vertical tube
W. Cullum,J. Reid,Karen Vierow +2 more
TL;DR: In this article, a counter current annular flow experiment was performed to determine flooding conditions for varying degrees of subcooling using steam and water, which can be used in reactor safety codes to provide an improved model of flooding during accident analysis.

Experimental study on interfacial and wall friction factors under counter-current flow limitation in vertical pipes with sharp-edged lower ends
TL;DR: In this paper, the authors performed experiments on air-water counter-current annular flows in circular vertical pipes of 20 and 40mm in diameter to obtain databases of the interfacial and wall friction factors.

Wall pressure measurements of flooding in vertical countercurrent annular air–water flow
Isaac Choutapalli,Karen Vierow +1 more
TL;DR: An experimental study of flooding in countercurrent air-water annular flow in a large diameter vertical tube using wall pressure measurements is described in this paper, where Axial pressure profiles along the length of the test section were measured up to and after flooding using fast response pressure transducers for three representative liquid flow rates representing a wide range of liquid Reynolds numbers.

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.
