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:

Experimental study on air-water countercurrent flow limitation in a vertical tube based on measurement of film thickness behavior
TL;DR: In this article, the authors used a parallel electrode probe to measure film thickness and obtained the time domain and frequency domain characteristics of liquid film to understand the triggering mechanism of gas-liquid counter-current flow limitation.

Study of gas-liquid upward annular flow through a contraction
S. Anupriya,Sreenivas Jayanti +1 more
TL;DR: In this article, the authors studied the response of vertical annular flow to a sudden or gradual pipe contraction and developed a semi-empirical model for the pressure loss coefficient in the contraction.

A fluid dynamics perspective on the flow dependent performance of honey comb microbial fuel cells
TL;DR: In this paper, the impacts of flow channel diameter on the performance of the HCMFCs operated in recirculation batch mode have been estimated in the current study, three different diameters like 0.4 cm, 0.7 cm and 1 cm are used in three reactors as HCMF1, HCM FC2 and HCMCFC3 respectively along with a control reactor devoid of flow straighteners.

Flow Patterns, Transitions and Models for Specific Flow Patterns
Barry J. Azzopardi,John Hills +1 more
TL;DR: In this paper, the authors present flow patterns, the configurations into which gas/liquid flows can arrange themselves in pipes and other geometries, and the effect of flow patterns on heat transfer and of heat transfer on flow patterns are considered.

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.
