A two-pressure model for slightly compressible single phase flow in bi-structured porous media [PDF]

open access: yes, 2012
Problems involving flow in porous media are ubiquitous in many natural and engineered systems. Mathematical modeling of such systems often relies on homogenization of pore-scale equations and macroscale continuum descriptions.

Coupling of two-phase flow in fractured-vuggy reservoir with filling medium

open access: yesOpen Physics, 2017
Caves in fractured-vuggy reservoir usually contain lots of filling medium, so the two-phase flow in formations is the coupling of free flow and porous flow, and that usually leads to low oil recovery.

Upscaled Lattice Boltzmann Method for Simulations of Flows in Heterogeneous Porous Media

open access: yesGeofluids, 2017
An upscaled Lattice Boltzmann Method (LBM) for flow simulations in heterogeneous porous media at the Darcy scale is proposed in this paper. In the Darcy-scale simulations, the Shan-Chen force model is used to simplify the algorithm. The proposed upscaled

Upscaling multi-component two-phase flow in porous media with partitioning coefficient [PDF]

open access: yes, 2011
This paper deals with the upscaling of multicomponents two-phase flow in porous media. In this paper, chemical potential equilibrium at the interface between both phases is assumed to be described by a linear partitioning relationship such as Raoult or ...
