Anisotropy of Thermal Dispersion in Porous Media.

Comparison of Thermal Dispersion Effects for Single and two Phase Analysis of Heat Transfer in Porous Media

The present work involves numerical simulation of a steady, incompressible forcedconvection fluid flow through a matrix of porous media between two parallel plates at constanttemperature. A Darcy model for the momentum equation was employed. The mathematical model forenergy transport was based on single phase equation model which assumes local thermal equilibriumbetween fluid and solid phases. ...

Saturation dependence of dispersion in porous media.

In this study, we develop a saturation-dependent treatment of dispersion in porous media using concepts from critical path analysis, cluster statistics of percolation, and fractal scaling of percolation clusters. We calculate spatial solute distributions as a function of time and calculate arrival time distributions as a function of system size. Our previous results correctly predict the range ...

Dispersion of solutes in porous media

A recently introduced theory of solute transport in porous media is tested by comparison with experiment. The solute transport is predicted using an adaptation of the cluster statistics of percolation theory to critical path analysis together with knowledge of how the structure of such percolation clusters affects the time of transport across them. Only the effects of a single scale of medium h...

Seepage and Thermal Effects in Porous Media

Quantifying the directional parameter of structural anisotropy in porous media.

A new method has been developed to define the directional parameter and characterize the structural anisotropy of a highly porous structure with extensive pore interconnectivity and surface area, such as scaffolds in tissue engineering. This new method called intercept segment deviation (ISD) was validated through the comparison of structural anisotropy from ISD measurements with mechanical ani...
