Modelling flow pattern transitions for steady upward gas-liquid flow in vertical tubes
TL;DR: In this paper, the authors developed models for predicting flow pattern transitions during steady gas-liquid flow in vertical tubes based on physical mechanisms suggested for each transition, incorporating the effect of fluid properties and pipe size.
Journal ArticleDOI
Drag reduction fundamentals
TL;DR: In this paper, the effects of dilute solutions of linear, random-coiling macromolecules in turbulent pipe flow is reviewed. And the experimental evidence is emphasized in three sections concerned with the graphical display of established features of the phenomenon, data correlation and analysis, and the physical mechanism of drag reduction.

The interrelation between void fraction fluctuations and flow patterns in two-phase flow
Owen C. Jones,Novak Zuber +1 more
TL;DR: In this paper, the probability density function (PDF) of the fluctuations in void fraction may be used as an objective and quantitative flow pattern discriminator for the three dominant patterns of bubbly, slug, and annular flow.

Slug flow regime identification from dynamic void fraction measurements in vertical air-water flows
G. Costigan,P.B. Whalley +1 more
TL;DR: In this paper, an existing design of conductivity probe for the measurement of void fraction has been developed and tested, and the probe's response to different void distributions supported the calibration results.
