Stochastic porous-medium equation in one dimension

open access: yesPhysical Review E
We study the porous medium equation (PME) in one space dimension in presence of additive non-conservative white noise, and interpreted as a stochastic growth equation for the height field of an interface. We predict the values of the two growth exponents $α$ and $β$ using the functional RG.

A Semi‐Analytical Solution for the Equivalent Permeability Coefficient of the Multilayered Porous Medium With Continuous Fracture

open access: yesWater Resources Research
Fractures significantly alter the permeability characteristics of the natural porous media, especially for the multilayered porous medium system. The most direct and effective approach to assess the hydraulic conductivity of a multilayered porous medium ...

Wasserstein geometry of porous medium equation

open access: yesAnnales de l'Institut Henri Poincaré C, Analyse non linéaire, 2012
We study the porous medium equation with emphasis on q -Gaussian measures, which are generalizations of Gaussian measures by using power-law distribution. On the space of q -Gaussian measures, the porous medium equation is reduced to an ordinary differential equation for covariance matrix ...

Exploration of peristaltic pumping of Casson fluid flow through a porous peripheral layer in a channel

open access: yesNonlinear Engineering, 2022
This article is aimed to investigate the peristaltic pumping of a two-layered model in a two-dimensional channel. The core region occupies Casson fluid, while the porous medium occupies the peripheral region.

On the stochastic porous medium equation

open access: yesJournal of Differential Equations, 2006
The author proves existence and uniqueness for the Cauchy problem and the initial-boundary value problem \[ u_{t}=\sum_{i=1}^{n}\partial_{x_{i}}(| u| ^{p-2}\partial_{x_{i}}u)+\sum_{j=1}^{\infty}f_{j}{dB_{j}\over dt},\quad (t,x)\in (0,T)\times G, \] \(u=0\), \((t,x)\in (0,T)\times\partial G\), \(u(0,x)=u_0(x)\), \(x\in G\), where \(G\) is a bounded ...

A combined collocation and Monte Carlo method for advection-diffusion equation of a solute in random porous media

open access: yesESAIM: Proceedings and Surveys, 2014
In this work, we present a numerical analysis of a method which combines a deterministic and a probabilistic approaches to quantify the migration of a contaminant, under the presence of uncertainty on the permeability of the porous ...

Combine effects of Magnetohydrodynamics (MHD) and partial slip on peristaltic Blood flow of Ree–Eyring fluid with wall properties

open access: yesEngineering Science and Technology, an International Journal, 2016
In this article, combine effects of Magnetohydrodynamics and partial slip on Blood flow of Ree–Eyring fluid through a porous medium have been investigated. The walls of the non-uniform porous channel are considered as compliant. The governing equation of
