Focusing of an elongated hole in porous medium flow
In the focusing problem, we study solutions to the porous medium equation ∂tu = (u) whose initial distributions are positive in the exterior of a compact 2D region and zero inside. We assume that the initial interface is elongated (i.e., has an aspect ratio > 1), and possesses reflectional symmetry with respect to both the xand y-axes. We implement a numerical scheme that adapts the numerical g...
متن کاملFlow-induced channelization in a porous medium
Flow through a saturated, granular, porous medium can lead to internal erosion, preferential flow enhancement, and the formation of channels within the bulk of the medium. We examine this phenomenon using a combination of experimental observations, continuum theory and numerical simulations in a minimal setting. Our experiments are carried out by forcing water through a Hele-Shaw cell packed wi...
متن کاملAn Analytical and Semi-analytical Study of the Oscillating Flow of Generalized Burgers’ Fluid through a Circular Porous Medium
Unsteady oscillatory flow of generalized Burgers’ fluid in a circular channel tube in the porous medium is investigated under the influence of time-dependent trapezoidal pressure gradient given by an infinite Fourier series. An exact analytical expression for the solution for the fluid velocity and the shear stress are recovered by using the similarity arguments together with the integral trans...
متن کاملOn the signed porous medium flow
We prove that the signed porous medium equation can be regarded as limit of an optimal transport variational scheme, therefore extending the classical result for positive solutions of [13] and showing that an optimal transport approach is suited even for treating signed densities.
متن کاملMathematical modeling of blood flow in a stenosed artery under MHD effect through porous medium
In this investigation, a mathematical model for studying oscillatory flow of blood in a stenosed artery under the influence of transverse magnetic field through porous medium has been developed. The equations of motion of blood flow are solved analytically. The analytical expressions for axial velocity, volumetric flow rate, pressure gradient, resistance to blood flow and shear stress have been...
