Numerical study of the process of unsteady flow in a three-layer porous medium
Magazine of Civil Engineering, 2023 The unsteady fluid flow in a three-layer porous medium is numerically investigated and is an important and topical problem. An analytical solution of the equation for the pressure fluid layer is obtained on the basis of the theory of elastic regime ...

, 2022 A porous medium can be defined as a material which contains spaces which, when continuous in some way, enable the movement of fluids, air and materials of different chemical and physical properties. The ability of a porous medium to permit the movement of fluids, air or a mixture of different fluids is related to porosity and the variability of pore ...

The instability of fronts in a porous medium [PDF]
Communications in Mathematical Physics, 1983 We use a random choice numerical method to analyze the instability of a front separating two fluids in a porous medium. We observe a linear instability and a catastrophic finite amplitude instability. A qualitative analogy with problems involving a transition to turbulence is pointed out.

, 2021 Flows through porous media can carry suspended and dissolved materials. These sediments may deposit inside the pore-space and alter its geometry. In turn, the changing pore structure modifies the preferential flow paths, resulting in a strong coupling between structural modifications and transport characteristics.

A fractional porous medium equation
Advances in Mathematics, 2011 We develop a theory of existence, uniqueness and regularity for a porous medium equation with fractional diffusion, $\frac{\partial u}{\partial t} + (- )^{1/2} (|u|^{m-1}u)=0$ in $\mathbb{R}^N$, with $m>m_*=(N-1)/N$, $N\ge1$ and $f\in L^1(\mathbb{R}^N)$.

A MODEL FOR POROUS-MEDIUM COMBUSTION
The Quarterly Journal of Mechanics and Applied Mathematics, 1989 Summary: A model of time-dependent porous-medium combustion is presented. The model is of combustion in a three-dimensional porous medium. The typical situation envisaged is the combustion of a non-deforming porous solid medium through which a gas such as air passes.
