Porous Media Analysis by Modified MLPG Formulations

Instability Analysis of Miscible Displacements in Homogeneous Porous Media

Absolute Permeability Calculation by Direct Numerical Simulation in Porous Media

Simulating fluid flow at micro level is an ongoing problem. Simplified macroscopic flow models like Darcy’s law is unable to estimate fluid dynamic properties of porous media. The digital sample reconstruction by high resolution X-ray computed tomography scanning and fluid-dynamics simulation, together with the increasing power of super-computers, allow to carry out pore-scale simulations throu...

Microstructure Analysis of Reconstructed Porous Media

We compare the quantitative microstructural properties of Berea Sandstone with stochastic reconstructions of the same sandstone. The comparison is based on local porosity theory. The reconstructions employ Fourier space ltering of Gaussian random elds and match the average porosity and two-point correlation function of the experimental model. Connectivity properties of the stochastic models dii...

Analysis of Vortex Motion in Porous Media

In vortex motion fluid moves in curve path and the stream lines are curved. When the fluid flows between curved stream line, the centrifugal forces are setup which is counter balanced by pressure forces acting in the radial direction. The vortex motion has two types of curved motion. The first type called free vortex type, the fluid moves due to its own natural effect but energy is not added to...

Connectivity selection by porous media: ”spectral chromatography”

This note discusses the behavior of polymers with arbitrary connectivity in small pores. For simplicity only cylindrical pores are considered. In contrast to linear polymers (spectral dimension = I) which fit into
