In-situ characterization of capillary pressure during three-phase flow in porous media [PDF]

open access: yesE3S Web of Conferences, 2023
We characterize the pore-scale fluid distributions, phase connectivity, and local capillary pressures during three-phase flow in a water-wet Berea sandstone sample.

Semi-Implicit Finite Volume Procedure for Compositional Subsurface Flow Simulation in Highly Anisotropic Porous Media

open access: yesFluids, 2021
Subsurface multiphase flow in porous media simulation is extensively used in many disciplines. Large meshes with non-orthogonalities (e.g., corner point geometries) and full tensor highly anisotropy ratios are usually required for subsurface flow ...

Numerical analysis of water-alternating-CO2 flooding for CO2-EOR and storage projects in residual oil zones

open access: yesInternational Journal of Coal Science & Technology, 2023
Residual oil zones (ROZs) have high residual oil saturation, which can be produced using CO2 miscible flooding. At the same time, these zones are good candidates for CO2 sequestration.

SPH Simulation of Interior and Exterior Flow Field Characteristics of Porous Media [PDF]

open access: yes, 2020
At the present time, one of the most relevant challenges in marine and ocean engineering and practice is the development of a mathematical modeling that can accurately replicate the interaction of water waves with porous coastal structures. Over the last

Numerical Study of Elasto-Plastic Hydraulic Fracture Propagation in Deep Reservoirs Using a Hybrid EDFM–XFEM Method

open access: yesEnergies, 2021
Rock yielding may well take place during hydraulic fracturing in deep reservoirs. The prevailing models based on the linear elastic fracture mechanics (LEFM) are incapable of describing the evolution process of hydraulic fractures accurately.

Numerical Study of the Effect of a Power-law Fluid Flow Structures on Levels of Mixing in a Taylor Couette Configuration [PDF]

open access: yesJournal of Applied Fluid Mechanics, 2023
This work is a numerical study on the effects of the flow structures of the power-law fluid between two concentric cylinders with an upward laminar axial flow on levels of mixing and mean residence time through the Taylor Couette system.

Fates of Emitted Particles Depending on Mask Wearing Using an Approach Validated Across Spatial Scales

open access: yesGlobal Challenges, 2023
The spread of emitted potentially virus‐laden aerosol particles is known to be highly dependent on whether a mask is worn by an infected person and on the emission scenario, i.e., whether the person is coughing, speaking, or breathing.

Deposition and transport of graphene oxide in saturated and unsaturated porous media [PDF]

open access: yes, 2013
In this work, sand and bubble column experiments were conducted to explore the deposition mechanisms of graphene oxide (GO) particles in porous media with various combinations of moisture content and ionic strength.

Analysis of the Brinkman equation as a model for flow in porous media [PDF]

open access: yes, 1987
The fundamental solution or Green's function for flow in porous media is determined using Stokesian dynamics, a molecular-dynamics-like simulation method capable of describing the motions and forces of hydrodynamically interacting particles in Stokes ...
