Spontaneously formed porous and composite materials [PDF]
, 2010 In recent years, a number of routes to porous materials have been developed which do not involve the use of pre-formed templates or structure-directing agents. These routes are usually spontaneous, meaning they are thermodynamically downhill.

Theory of Filtration in a Double Porosity Medium
Doklady Earth Sciences, 2019 This paper defines a generalized mathematical model of filtration in a double porosity medium, taking into ac- count recent ideas on liquid and gas flow in rocks with an anomalously low permeability (including nanoporous rocks). The obtained generalized equation takes into consideration, in contrast to the classical model, the integral effects of ...

The Global Kondaurov Double Porosity Model
DEStech Transactions on Computer Science and Engineering, 2017 In this paper we derive a non-equilibrium matrix imbibition equation for the homogenized Kondaurov double porosity model which is valid for arbitrary relaxation times. This equation involves the real saturation and Kondaurov's non-equilibrium parameter, i.e., the principal unknowns of the model.

Derivation of models of compressible miscible displacement in partially fractured reservoirs
Electronic Journal of Differential Equations, 2007 We derive rigorously homogenized models for the displacement of one compressible miscible fluid by another in fractured porous media. We denote by $epsilon$ the characteristic size of the heterogeneity in the medium.

Double porosity model to describe both permeability change and dissolution processes
Mechanical Engineering Journal, 2015 Cement is a practical material for constructing the geological disposal system of radioactive wastes. The dynamic behavior of both permeability change and dissolution process caused by a high pH groundwater was explained using a double porosity model ...
