Nov 28, 2013 · The results demonstrate that roughness impacts phase distribution, flow regimes, and phase relative permeability (a measure of phase interference); roughness increases …

May 3, 2023 · This study further develops the two-phase flow structure identification template by introducing a fracture surface roughness parameter to enable the two-phase flow pattern …

Nov 8, 2017 · The effect of invasion pressure of crude oil, roughness of fracture wall, and wettability of the wall on two-phase flow in rough-walled fracture is evaluated.

Sep 1, 1990 · From these observations it is clear that the roughness on the tube wall does interact with the gas component of the flow to reduce the minimum bubble size near the wall, and this …

Mar 30, 2006 · In this study, we suggest a new approach to describe relative permeability behavior in rough-walled fractures based on experimental observations of two-phase flow …

Roughness of the fracture walls is important in single phase flow because it increases friction and causes streamlines to be crooked even in laminar flow. In two- (or multi-) phase flow, wall …

Dec 1, 2014 · The results demonstrate that roughness impacts phase distribution, flow regimes, and phase relative permeability (a measure of phase interference); roughness increases …

Nov 8, 2017 · To describe accurately the flow characteristic of fracture scale displacements of immiscible fluids, an incompressible two-phase (crude oil and water) flow model incorporating …

Dec 1, 2014 · Despite some successful studies of two‐phase or unsaturated flows in ideal smooth‐walled fractures, the more realistic issues regarding fundamentals of two‐phase …

To describe accurately the flow characteristic of fracture scale displacements of immiscible fluids, an incompressible two-phase (crude oil and water) flow model incorporating interfacial forces …
