Grid Generation Issues in the CFD Modelling of Two-Phase Flow in a Pipe
TL;DR: The grid generation issues found in the 3D simulation of two-phase flow in a pipe using Computational Fluid Dynamics (CFD) are discussed in this paper, showing that there is a strong dependency of the flow behaviour on the mesh employed.
Journal ArticleDOI
The monitoring of the two phase flow-annular flow type regime using microwave sensor technique
TL;DR: In this article, the authors report on the development of a novel non-intrusive sensor, which is based on electromagnetic waves cavity resonator, which determines and monitors the percentage volumes of each of the two phases (oil and gas) in the pipeline using the resonant frequencies shifts that occur within the resonator.

Comparison between wire mesh sensor and gamma densitometry void measurements in two-phase flows
TL;DR: In this paper, a 16 × 16 WMS was used with high spatial and temporal resolutions to test both the capacitance and conductance WMS against a gamma densitometer (GD).

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.

A new electrode-mesh tomograph for gas–liquid flows
TL;DR: In this article, an electrode-mesh tomograph for high-speed visualisation of transient gas fraction distributions in two-phase flows in pipes is presented, which is based on the measurement of the local instantaneous conductivity of the 2-phase mixture.

Measuring techniques in gas–liquid and gas–liquid–solid reactors
TL;DR: In this paper, an overview of multiphase flow metering techniques for gas/liquid analysis can be found, including nonintrusive techniques that deliver global, cross-section-averaged or local data.
