Analysis of Two-Phase Gas–Water Flow in Carbonate Reservoirs
Journal of Mining Science, 2018Gas–water relative permeability (GWRP) is measured in the tests of full-diameter cores. Based on the obtained GWRP curves, the standard normalized curves are plotted for three types of carbonate reservoirs: matrix pore, fracture and solution pore. The corresponding gas and water two-phase flow model was deduced by considering stress sensitivity and non-

Compositional Modeling of Two-Phase (Gas/Water) Flow in Pipes
SPE Journal, 2009Summary The current work presents a fully compositional tool for modeling systems exhibiting two-phase (gas/water) flow. The tool couples complex hydrodynamic and thermodynamic models to describe the behavior of fluids flowing in a pipe. The model described herein focuses on gas transmission with low-liquid loading conditions (hl/d & ...

Gas-water two-phase flow pattern recognition based on ERT and ultrasound Doppler
2018 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2018Two phase flow is widely encountered and of high importance in the manufacturing process and related scientific research. The two-phase flow process is complex, and the flow patterns are jointly determined by the phase fraction and the flow rate. The traditional way of studying the flow patterns uses a single sensor, generally sensing one point, to ...

Comparative study of gas–oil and gas–water two-phase flow in a vertical pipe
Chemical Engineering Science, 2010Abstract A wire-mesh sensor has been employed to study air/water and air/silicone oil two-phase flow in a vertical pipe of 67 mm diameter and 6 m length. The sensor was operated with a conductivity-measuring electronics for air/water flow and a permittivity-measuring one for air/silicone oil flow. The experimental setup enabled a direct comparison of

Flow field simulation of gas-water two phase flow in annular channel
AIP Conference Proceedings, 2014The gas-water two-phase flow is very common in the industrial processes. the deep understanding of the two-phase flow state is to achieve the production equipment design and safe operation. In the measurement of gas-water two-phase flow, the differential pressure sensor is widely used, and some measurement model of multiphase flow have been concluded ...

Flow Pattern Identification of Gas/Water Two Phase Flow Based on SVM
2006 6th World Congress on Intelligent Control and Automation, 2006Based on the conductance fluctuating signals measured from gas/water two-phase flow in vertical upward pipe, the 10 feature quantities, which reflect flow characteristics of gas/water two-phase flow, were extracted. The features in frequency domain were derived by using linear prediction method of speech signal processing and the features in time ...

Gas-water two-phase flow pattern characterization with Multivariate Multiscale Entropy
2013 IEEE International Conference on Imaging Systems and Techniques (IST), 2013Gas-liquid two-phase flow is a commonly encountered multiphase flow phenomena in process industries. The flow behavior of each typical flow pattern is urged to know in order to further understand its inherent flow mechanism. This paper aims to characterize the flow pattern of gas-water two-phase flow within a horizontal pipe by the Multivariate ...

Heat transfer without phase change of gas-water two-phase flow in microgap
2016 17th International Conference on Electronic Packaging Technology (ICEPT), 2016Since the higher function and miniaturized electronic devices need to consume more energy, the heat flux of local area in device will be more than 1000 w/cm2 to cause the concern of heat transfer. This paper studied the heat transfer of air-water two-phase flow in microgap with non-boiling conditions. When the flow rate of DI water was fixed (32∼196 ml/

CFD Simulation of Gas-Water Two-Phase Flow in Turbocharger
2009A turbocharger is widely used by industry as an efficient thermal performance enhancement device, and its efficiency is often dependent on the conditions and properties of the working fluid. One industry problem is the use of low-grade diesel, that produces various combustion products, and thus causes blade throat blockage, blade corrosion, damage, etc.

Design of internal structures of conductance sensors for gas-water two-phase flow measurement
AIP Conference Proceedings, 2012Conductance sensor array is widely used in measuring two-phase flow parameters, in this paper we propose a new configuration of conductance sensors with six rectangular electrodes of same size from the pipe facing to an inner ring-type electrode and use it to measure gas cross-sectional-averaged water holdup value.
