Downward Annular Flow of Air–Oil–Water Mixture in a Vertical Pipe

Energies, 2020
The paper presents the results of a study concerned with the hydrodynamics of an annular downward multiphase flow of gas and two mutually non-mixing liquids through a vertical pipe with a diameter of 12.5 mm.

A Fast Algorithm to Simulate Droplet Motions in Oil/Water Two Phase Flow

Procedia Computer Science, 2017
Abstract To improve the research methods in petroleum industry, we develop a fast algorithm to simulate droplet motions in oil and water two phase flow, using phase field model to describe the phase distribution in the flow process. An efficient partial difference equation solver—Shift-Matrix method is applied here, to speed up the calculation coding

Permeabilities of Water–Oil Two-Phase Flow in Capillary Fractures with Different Wettabilities

Energies
The influence of wettability on the permeability performance of water–oil two-phase flow has attracted increasing attention. Dispersed flow and stratified flow are two flow regimes for water–oil two-phase flow in capillary fractures.

Study on the Ability and Heterogeneity of Oil Water Two-Phase Flow in Sandstone

, 2023
Abstract It is difficult to analyze the heterogeneity of sandstone reservoir and the seepage law of multi-phase fluid in Porous medium. Traditional experimental methods are difficult to accurately characterize the multi-phase flow and seepage characteristics of heterogeneous sandstone.

Dissipative Particle Dynamic Simulation of Oil-Water Two-Phase Flow in Quartz Slits

Geofluids, 2023
Aiming to study the characteristics and mechanism of oil-water two-phase flow, based on the method of dissipative particle dynamics (DPD), meso-scale models of pressure-driven flow in quartz slits with width of 5-15 nm were simulated.

Prediction of pressure drop in multiphase horizontal pipe flow [PDF]

, 2006
Empirical correlations were tested against reliable two phase pipe flow data for the prediction of pressure drop. Correlations are recommended for the prediction with stratified and annular type flows.

Hydrodynamics of air and oil–water dispersion/emulsion in horizontal pipe flow with low oil percentage at low fluid velocity

Cogent Engineering, 2018
The objective of this paper is to investigate the flow regimes of three phase flow, emerged to be as two phase flow. These two phases are air phase and oil dispersed in water phase, in other words the latter phase can be termed as water–oil emulsion ...

Translophagy—A potential link between autophagy impairment and translational errors

FEBS Letters, EarlyView.
Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

Large probe arrays for measuring mean and time dependent local oil volume fraction and local oil velocity component distributions in inclined oil-in-water flows [PDF]

, 2013
Arrays of dual-sensor and four-sensor needle conductance probes have been used to measure the mean and time dependent local properties of upward inclined, bubbly oil-in-water flows (also known as dispersed oil-in-water flows) in a 153mm diameter pipe ...
