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

Deformation and rupture of microcapsules flowing through constricted capillary
Scientific Reports, 2021 The dynamics of deformable microcapsules flowing through constricted channels is relevant in target delivery of chemicals in physiological systems, porous media, microfluidic medical diagnostic devices and many other applications. In some situations, the

Nonextensive diffusion as nonlinear response [PDF]
, 2005 The porous media equation has been proposed as a phenomenological ``non-extensive'' generalization of classical diffusion. Here, we show that a very similar equation can be derived, in a systematic manner, for a classical fluid by assuming nonlinear ...

, 1994 A family of finite elements for two-dimensional, three-dimensional and axisymmetric finite deformation of porous media has been implemented into DIANA. This implementation includes two extensions of Biot’s theory: one for swelling media, the other for blood perfused soft tissue.

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

Immobilized Particles in Gel Matrix-Type Porous Media. Homogeneous Porous Media Model [PDF]
Biotechnology Progress, 2001 Diffusion in pure gels and gels with immobilized cells was analyzed. A model of diffusion assuming a homogeneous cell distribution in gel was improved by introducing a tortuosity value. By theoretical analysis and numerical modeling it was shown that the tortuosity of a gel with immobilized cells is the product of two factors: (1) tortuosity generated ...

Research on carbonate reservoir interwell connectivity based on a modified diffusivity filter model
Open Physics, 2017 According to the solution of dual-porosity model, a diffusivity filter model of carbonate reservoir was established, which can effectively illustrate the injection signal attenuation and lag characteristic.
