Numerical and experimental analysis of ultrasound attenuation in oil-water two-phase flow
2017 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2017Measuring the process parameters of multiphase flow has remained a widely discussed topic within the field of multiphase flow. The measurement of phase fraction of oil-water two-phase flow with ultrasound attenuation is very difficult due to the nonlinear response to the measuring parameters, and the main attenuation mechanisms are influenced by ...

Velocity measurement of oil-water two-phase flow based on Ultrasonic Doppler
2017 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2017For the overall superficial velocity measurement of oil-water two-phase flow in horizontal pipeline, using Continuous Wave Ultrasonic Doppler (CWUD) technique, a calculation model considering the influence of holdup distribution is proposed. A CWUD system is composed of a pair of piezoelectric ceramic ultrasonic transducers with center frequency of ...

Ultrasonic forward modeling of industrial oil–water two-phase flow
UltrasonicsUltrasonic tomography (UT) is a non-invasive and radiation-free imaging technique for oil-water flow monitoring for its fast-acquisition and low-cost features. Conventional UT utilizes ray-based models, which simplify the ultrasonic wave propagation by neglecting wave-related phenomena such as refraction and interference.

A Model for Temperature Prediction for Two-Phase Oil/Water Stratified Flow
Journal of Energy Resources Technology, 2013In this paper a mathematical model was developed to predict temperature profiles for two-phase oil-water stratified flows. Based on the energy balance of a control volume, analytical solutions were derived for the prediction of temperature profiles for two-phase oil/water stratified flow pattern in pipe flows.

Experimental study of oil–water two-phase flow in a capillary model
Journal of Petroleum Science and Engineering, 2013Abstract The flow and mobilization of an oil slug surrounded by water in a unique capillary tube model is experimentally investigated in this research. A single oil slug with different lengths is mobilized under stationary conditions. It is found in the investigation that the development of a water film between the tube wall and the oil slug is ...

Water layer height measurement in oil-water two-phase flows
AIP Conference Proceedings, 2012Water layer height was measured by a single-wire capacitance probe in horizontal oil-water two-phase flows. The viscosity of oil was up to 140 mPa·s to simulate the actual flow in oil production logging. Typical water-layer-height curves with time were obtained when water was continuous. The accuracy was estimated by a quick-closing valve (QCV) system.

A Unified Model of Oil/Water Two-Phase Flow in the Horizontal Wellbore
SPE Journal, 2016Summary In this article, a more-general flow-pattern classification of oil/water two-phase flow in the horizontal wellbore is proposed first according to the theoretical analysis and previous research achievements, on the basis of which a simplification is then performed through reasonable incorporation, and the ultimate flow patterns

Characterization of oil/water two-phase flow based on complexity theory
Proceedings of 2004 International Conference on Machine Learning and Cybernetics (IEEE Cat. No.04EX826), 2005The flow patterns of oil/water two-phase flow in vertical upward pipes have been characterized by the analysis of LZ complexity and fluctuation complexity measures using the conductance time series fluctuating signals. It is shown that both complexity measures have little changes with oil-in-water flow pattern variations for flow conditions of 61%/spl ...

Complex network analysis in inclined oil–water two-phase flow
Chinese Physics B, 2009Complex networks have established themselves in recent years as being particularly suitable and flexible for representing and modelling many complex natural and artificial systems. Oil–water two-phase flow is one of the most complex systems. In this paper, we use complex networks to study the inclined oil–water two-phase flow.

Pressure Drop for Oil-Water Two-phase Flow in Horizontal Pipe
AIP Conference Proceedings, 2010Pressure drops were measured during the co‐current flow of a mechanical oil and tap water in 40 mm inner diameter horizontal test section made from organic glass. Measurements is conducted were made for the oil superficial velocity ranges from 0.04 to 1.2 m/s and the water superficial velocity from 0.04 to 2.2 m/s.
