Overview of Oil-water Two-phase Flow Pressure Drop Theory

Academic Journal of Science and Technology, 2023
This is a review of the existing pressure drop theories for dispersed and annular flow in oil and water phases in straight wells is presented. The flow classification criteria, pressure drop calculation methods are outlined. For the dispersed flow, the homogeneous flow model and the two-fluid model are introduced.

Oil-in-Water Two-Phase Flow Pattern Identification From Experimental Snapshots Using Convolutional Neural Network

IEEE Access, 2019
The flow pattern is one of the most significant parameters in modeling the oil–water two-phase system. How to extract efficient and objective features to precisely identify the oil–water two-phase flow patterns is still a significant issue.

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

IEEE 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.

Numerical study and sensitivity analysis of two-phase oil-water flow and heat transfer in different flowline orientations using OpenFOAM

Case Studies in Thermal Engineering, 2022
Evaluating the oil-water temperatures in flowlines is demanding mostly in deep offshore applications where flow assurance issues and dramatic heat transfer are anticipated to occur. Consequently, a 3-D mathematical model of oil-water Newtonian flow under

Numerical Simulation of Oil-water Two-phase Flow Interface Tracking

Journal of Physics: Conference Series, 2023
Abstract The insulation performance of transformer oil has a great connection with the stable operation of power systems, and transformer oil will inevitably be mixed with water and other impurities in the actual operation. To explore the mechanism of the influence of suspended water droplets on the insulation performance of transformer ...
