Salinity Independent Flow Measurement of Vertical Upward Gas-Liquid Flows in a Small Pipe Using Conductance Method

open access: yesSensors, 2020
Flow measurement in gas-liquid two-phase flow is always a challenging work, because of the non-uniform phase distribution, severe slippage effect between phases, and different flow structures.

Two-phase Flow Model and Productivity Evaluation of Gas and Water for Dual-Medium Carbonate Gas Reservoirs

open access: yesFrontiers in Earth Science, 2022
Fluid flow in the dual-medium carbonate gas reservoir is characterized by stress sensitivity and non-Darcy flow effect. In order to accurately describe the unsteady flow of gas and water in the dual-medium gas reservoir, a two-phase flow model of gas and

New Algorithm to Discriminate Phase Distribution of Gas-Oil-Water Pipe Flow With Dual-Modality Wire-Mesh Sensor

open access: yesIEEE Access, 2020
Three-phase gas-oil-water flow is an important type of flow present in petroleum extraction and processing. This paper reports a novel threshold-based method to visualize and estimate the cross-sectional phase fraction of gas-oil-water mixtures.

Experimental and theoretical study of the gas–water two phase flow through a conductance multiphase Venturi meter in vertical annular (wet gas) flow [PDF]

open access: yes, 2011
Annular gas–liquid two phase flow widely occurs in nuclear industry. Various combinations of techniques have been employed in annular gas–liquid two phase flows to measure the flow parameters (e.g. liquid film thickness, gas volume fraction and the phase

Effect of channel geometries on two-phase mixture level swell and its fluctuation amplitude

open access: yesMechanical Engineering Journal, 2020
Gas–liquid two-phase flow in a stagnant pool is an important phenomenon in designing and operating industrial facilities. When gas is mixed or boiling occurs in stagnant water, the actual water level appears higher than the original water level.

The Recognition Algorithm of Two-Phase Flow Patterns Based on GoogLeNet+5 Coord Attention

open access: yesMicromachines, 2023
The two-phase flow in a microchannel consists of liquid–liquid and gas–liquid material components. The automatic recognition of flow patterns using deep learning approaches has been emerging.

Fracturing fluid imbibition impact on gas-water two phase flow in shale fracture-matrix system

open access: yesNatural Gas Industry B, 2023
A large amount of fracturing fluid in hydraulic fracturing is imbibed into the shale fracture/matrix, which leads to significant uncertainty in gas recovery evaluation. The mechanism of imbibition impact on the gas–water flow is not well understood.

Two-Phase Flow Model for Numerical Investigation of Impact of Water Retention on Shale Gas Production

open access: yesGeofluids, 2021
In this work, a triple-porosity, two-phase flow model was established to fill the knowledge gap of previous models focusing on gas production characteristics while ignoring the impacts of water injection.

Critical characteristics of an airlift pump for dredging

open access: yesFrontiers in Earth Science, 2022
There are many factors that affect an airlift pump for dredging. In actual applications, if these factors cannot be fully considered, the performance of the airlift pump will be reduced. In view of this, based on the critical model of the water–solid two-
