HOW LONG DOES IT TAKE FOR A GAS TO FILL A POROUS CONTAINER
(AMER MATHEMATICAL SOC, 1994)
Let us consider the problem u(t)(x, t) = Delta u(m)(x, t) for (x,t) epsilon D x [0, +infinity), u(x, 0)= u(0)(x) for x epsilon D, and (partial derivative u(m)/partial derivative n)(x, t) = h(x, t) for (x, t) epsilon partial ...
Pulsatile flow between two coaxial porous cylinders with slip on inner cylinder for large frequency of pulsation.
(2011-10-13)
The unsteady component of axial flow of an incompressible fluid in the region lying between the annular spaces of two coaxial cylinders has been investigated. The outer cylinder is assumed to possess uniform permeability ...
Pulsatile flow between two coaxial porous cylinders with slip on inner cylinder.
(2011-10-13)
A fully developed, axisymmetric, pulsatile motion of an incompressible Newtonian fluid,under the action of an oscillatory pressure gradient, has been considered in this work. The fl ow is assumed to take place in the ...
Titanium-35niobium alloy as a potential material for biomedical implants: in vitro study
(Elsevier B. V., 2015-11-01)
Research on new titanium alloys and different surface topographies aims to improve osseointegration. The objective of this study is to analyze the behavior of osteogenic cells cultivated on porous and dense samples of ...
Discontinuous Galerkin approximation of two-phase flows in heterogeneous porous media with discontinuous capillary pressures
(ELSEVIER SCIENCE SA, 2010)
We design and investigate a sequential discontinuous Galerkin method to approximate two-phase immiscible incompressible flows in heterogeneous porous media with discontinuous capillary pressures. The nonlinear interface ...
An exact equation for the free surface of a fluid in a porous medium
(Siam Publications, 2007-01-01)
We study the problem of the evolution of the free surface of a fluid in a saturated porous medium, bounded from below by a. at impermeable bottom, and described by the Laplace equation with moving-boundary conditions. By ...
